A month ago I put my two cents into the discussion going on “here”:http://www2.iro.umontreal.ca/~paquetse/cgi-bin/om.cgi?Research_Blogs/Self-Organizing_Directory_Development about what an ideal database of research weblogs would look like. Lots of interesting ideas on the page but I don’t know, alas, if any development is actually going ahead. I wish I had the expertise to do something myself. Maybe someone will pick up the ball during the summer break?
See this page for more postings about weblog metadata.
