No time to write much now, but here’s another site that does something like the [[Topic Exchange]] (with a medical focus). I think it uses Movable Type’s ‘standalone trackback’ CGI. Good to see others getting in on the act.

I wonder if I should open the Topic Exchange source and try and encourage others to do this, or if I should try and push people towards using topicexchange.com. Hmm. Any Python coders out there willing to help improve the ITE if I open the code?
