Topics in weblogs
Seth Ladd’s SemErgence weblog (which I found thanks to Jamie Pitts, whom I discovered because he listed himself on the wiki page I set up a few hours ago) has been concerning itself with topics in weblogs lately. It will be interesting to see where these efforts will lead - presumably it will turn out a little different from the Internet Topic Exchange and K-collector efforts, given the RDF bent.

Speaking of the Topic Exchange, next month I will be presenting a paper about it by Phil Pearson and myself, titled “A Topic Sharing Infrastructure for Weblog Networks” (pdf, 500k), at the Communication Networks and Services Research conference.

The European Collaborative for Communities of Practice (ECCoP) has a weblog, they focus on “collaborative action-research”. I briefly sift though some post. I especially like the post about the “Horizontalization of Learning” phrased by Etienne Wenger.

“The quote refers to the need for associations to pay attention to the now critical role of engagement among their members. This engagement and the resulting knowledge sharing is an effective way for associations to cater to their members’ need for knowledge, appropriate to a world in which knowledge development is distributed and all members have access, via technology, to anyone anywhere anytime.” [more]
