Digital Campus #26 - Free for All

Thursday, May 8th, 2008

On this episode of the Digital Campus podcast we wrestle with how to keep open access/open source educational resources and tools sustainable for the long run. Mills elaborates on some of his ideas about a “freemium” business model for higher ed, and Tom and I explain the dilemma from the perspective of large academic software projects. We also debate whether laptops are a distraction in the classroom, among other topics in the news roundup and picks of the week. [Subscribe to this podcast.]

Washington Post on Zotero, Open Academia

Tuesday, January 1st, 2008

It was nice to see the Zotero project covered on the front page of the Washington Post yesterday in the article “Internet Access Is Only Prerequisite For More and More College Classes.” Also nice to see a quotation at the end of the article from yours truly about the movement in higher ed toward open tools and resources.

The Strange Dynamics of Technology Adoption and Promotion in Academia

Monday, November 5th, 2007

Kudos to Bruce D’Arcus for writing the blog post I’ve been meaning to write for a while. Bruce notes with some amazement the resistance that free and open source projects like Zotero meet when they encounter the institutional buying patterns and tech evangelism that is all too common in academia. The problem here seems to be that the people doing the purchasing of software are not the end users (often the libraries at colleges and universities for reference managers like EndNote or Refworks and the IT departments for course management systems) nor do they have the proper incentives to choose free alternatives.

As Roy Rosenzweig and I noted in Digital History, the exorbitant yearly licensing fee for Blackboard or WebCT (loathed by every professor I know) could be exchanged for an additional assistant professor–or another librarian. But for some reason a certain portion of academic technology purchasers feel they need to buy something for each of these categories (reference managers, CMS), and then, because they have invested the time and money and long-term contracts on those somethings, they feel they need to exclusively promote those tools without listening to the evolving needs and desires of the people they serve. Nor do they have the incentive to try new technologies or tools.

Any suggestions on how to properly align these needs and incentives? Break out the technology spending in students’ bills (”What, my university is spending that much on Blackboard?”)?

Nineteenth-Century Open Source

Thursday, August 2nd, 2007

Shaker chairNear where we’re staying on vacation there is a small but excellent Shaker museum. As a historian who in part studies nineteenth-century religion, I know a bit about the Shakers, one of the more remarkable and unusual revival Christian sects. (Note to those wishing to create a new sect that flourishes: eschew celibacy, even if you do make amazing furniture.) It is easy to think of the Shakers as from another age (or perhaps world), living in massive “families” of 50 to 100 “brothers and sisters” and focusing on the simple life of agriculture and crafts (in addition to very serious and often ecstatic forms of worship). But the museum brings to life the Shakers’ less well-known technological sophistication. They were innovators of the first order, constantly refining the efficiency of their families’ production (the simple lines of Shaker furniture made them easier to clean, important when your dining room seats 100).

What really struck me was their patented technologies. That’s right, the sect occasionally took advantage of U.S. patent law. The Shaker family near us invented a massive, semi-automated washing machine, among other things. And what they did with their patents is most interesting. They patented these machines so that no one would steal the designs, and then they licensed the designs for free to other Shaker communities, which did the same in return with their innovations. Sound familiar?

2007 Mellon Awards for Technology Collaboration

Wednesday, March 14th, 2007

The Andrew W. Mellon Foundation has launched the nominating process for the second annual Mellon Awards for Technology Collaboration (MATC). The awards, given by tech luminaries such as Tim Berners-Lee and Vint Cerf, honor not-for-profit organizations for leadership in the collaborative development of open source software tools with particular application to higher education and not-for-profit activities.

Creating a Blog from Scratch, Part 8: Full Feeds vs. Partial Feeds

Thursday, January 11th, 2007

One seemingly minor aspect of blogs I failed to consider carefully when I programmed this site was the composition of its feed. (Frankly, I was more concerned with the merely technical question of how to write code that spits out a valid RSS or Atom feed.) Looking at a lot of blogs and their feeds, I just assumed that the standard way of doing it was to put a small part of the full post in the feed—e.g., the first 50 words or the first paragraph—and then let the reader click through to the full post on your site. I noticed that some bloggers put their entire blog in their feed, but as a new blogger—one who had just spent a lot of time redesigning his old website to accommodate a blog—I couldn’t figure out why one would want to do that since it rendered your site irrelevant. It may seem minor, but a year later I’ve realized that there is, in part, a philosophical difference between a full and partial feed. Choosing which type of feed you are going to use means making a choice about the nature of your blog—and, surprisingly, the nature of your ego too. Subscribers to this blog’s feed have probably noticed that as of my last post I’ve switched from a partial feed to a full feed, so you already know the outcome of the debate I’ve had in my head about this distinction, but let me explain my reasoning and the advantages and disadvantages of full and partial feeds.

Putting the entire content of your blog into your feed has many practical advantages. Most obviously, it saves your readers the extra step of clicking on a link in their feed reader to view your full post. They can read your blog offline as well as online, and more easily access it on a non-computer device like a cell phone. Machine audiences can also take advantage of the full feed, searching it for keywords desired by other machines or people. For instance, most blog search engines allow you to set up feeds for posts from any blogger that contain certain words or phrases.

More important, providing a full feed conforms better with a philosophy I’ve tried to promote in this space, one of open access and the sharing of knowledge. A full feed allows for the easy redistribution of your writing and the combination of your posts with others on similar topics from other bloggers. A full feed is closer to “open source” than a feed that is tied to a particular site. For this reason, until the advent of in-feed advertising, most professional bloggers had partial feeds so readers would have to view advertising next to the full text of a post.

Even from the perspective of a non-commercial blogger—or more precisely the perspective of that blogger’s ego—full feeds can be slightly problematic. A liberated, full feed is less identifiably from you. As literary theorists know well, reading environments have a significant impact on the reception of a text. A full feed means that most of your blog’s audience will be reading it without the visual context of your site (its branding, in ad-speak), instead looking at the text in the homogenized reading environment of a feed reader. I’ve just switched from NetNewsWire to Google Reader to browse other blogs, and I especially like the way that Google’s feed reader provides a seamless stream of blog posts, one after the other, on a scrolling web page. I’m able to scan the many blogs I read quickly and easily. That reading style and context, however, makes me much less aware of specific authors. It makes the academic blogosphere seem like a stream of posts by a collective consciousness. Perhaps that’s fine from an information consumption standpoint, but it’s not so wonderful if you believe that individual voices and perspectives matter a great deal. Of course, some writers cut through the clutter and make me aware of their distinctive style and thoughts, but most don’t.

At the Center for History and New Media, we’ve been thinking a lot about the blog as a medium for academic conversation and publication—and even promotion and tenure—and the homogenized feed reader environment is a bit unsettling. Yes, it can be called academic narcissism, but maintaining authorial voice and also being able to measure the influence of individual voices is important to the future of academic blogging.

I’ve already mentioned in this space that I would like to submit this blog as part of my tenure package, for my own good, of course, but also to make a statement that blogs can and should be a part of the tenure review process and academic publication in general. But tenure committees, which generally focus on peer-reviewed writing, will need to see some proof of a blog’s use and impact. Right now the best I can do is to provide some basic stats about the readership of this blog, such as subscriptions to the feed.

But with a full feed, you can slowly loose track of your audience. Providing your entire posts in the feed allows anyone to resyndicate it, aggregate it, mash it up, or simply copy it. I must admit, I am a little leery of this possibility. To be sure, there are great uses for aggregation and resyndication. This blog is resyndicated on a site dedicated to the future of the academic cyberinfrastructure, and I’m honored that someone thought to include this modest blog among so many terrific blogs charting the frontiers of libraries, technology, and research. On the other hand, even before I started this blog I had experiences where content from my site appeared somewhere else for less virtuous reasons. I don’t have time to tell the full story here, but in 2005 an unscrupulous web developer used text from my website and a small trick called a “302 redirect” to boost the Google rankings of one of his clients. It was more amusing than infuriating—for a while a dentist in Arkansas had my bio instead of his. More seriously, millions of spam blogs scrape content from legitimate blogs, a process made much easier if you provide a full feed. And there are dozens of feed aggregators that will create a website from other people’s content without their permission. Regardless of the purpose, above board or below, I have no way of knowing about readers or subscribers to my blog when it appears in these other contexts.

But these concerns do not outweigh the spirit and practical advantages of a full feed. So enjoy the new feed—unless you’re that Arkansas dentist.
