Russell Beattie points to a cool project, TagSurf, which has some resemblance to Frassle. It's all links, tags, and messages. In Frassle, the organizing principle is links: you make a comment by creating a blog post whose title links to my blog post; two categories or blogs are associated when they link to a lot of the same stuff. TagSurf, as its name would imply, is organized around (shared) tags. But also around links - you can get a set of responses to a given URL.

I should spend some more time grokking TagSurf and seeing whether it's worthwhile to copy some of its features.
