Interconnected

Two good linking toys are the totally connected HyperDictionary, and firmament.to [via scribot] which turns the www inside-out.

(Speaking of which, I met Tim Hall the other night and he mooted that weblogs were an inside-out Usenet. That Usenet hangs conversation threads off posts made by people, the threads classified by topic; that weblogs hangs comments threads off posts of single topics, classified by person.)
