Good ideas and projects abound. Finding ways to note, annotate, and review them is an open problem. Finding ways to let people working on them work together and not separately, likewise. Khaled prefers a bit of software that privileges individual ideas and allows discussion of it, to an open wiki.
I feel strongly the aggregate benefit of having eveyrone do everything on a single revisioned system with shared messaging and recent changes; but aside from that think the idea of a specialized interface is great. What are simple ways to encourage people who hate wikis to come leave ideas, and revisit commentary later? Ways to integrate mailing list threads with longer lived wikitext? A mail-to-wiki gateway? (vice-versa is already implemented, after a fashion, with the latest eNotif.) Suggestions welcome.
