Selected papers from the First Monday Conference, FM10 Openness: Code, Science and Content, are available in the June issue! More papers from the Conference will appear in July.

People differ in their willingness to share, as well as their reasons to do so. An open collaboration community of willing sharing members thrives on a virtuous cycle: increased sharing often offers stronger reasons for more people to share. However, it may also decline when the cycle goes the opposite direction and turns vicious. What determines the dividing line? We offer insights into this important question based on an analytic understanding of the concept of rational sharing, which is sharing for net gain in personal utility. In a nutshell, a community thriving on rational sharing is essentially an economic system, a platform for creating mutual benefit through exchanges.

Interesting discussion about making OPML dynamic like the RSS feeds that an OPML file aggregates.  This would allow the distribution model of OPML to be changed to a subscription model.  In TagIt, we've sort of got this without having to change the way feed readers work.  Since a bibliography is capable of creating an RSS feed, they already can be read by the feed readers dynamically -- that is, the readers can get new content as the bibliography is updated.  And since the bibliography topics themselves are simply posts, they can be consumed via RSS.  The only things I'd need to do in the code is

• update the timestamp on the bibliography topic whenever a component is added or edited
• give access to an rss feed of just the bibliography topics (by user or by TagIt instance)
