What is Conclave? Good question, it's hard to label since it's not like anything I've seen before. It's a wiki married with topic maps with a dash of weblog in there somewhere. Each page is a topic that forms typed associations with other pages and categories. For example, a page might have a creator relation with a user page, or a organise relation with a category page.
It's the brainchild of Guy Murphy, a very smart person I had the pleasure and privilege of working with at Calaba. Keep watching, because I think Conclave has a lot of potential and will probably change the way we think about wikis and their ilk.
