TiddlyWiki is a pretty slick site er web page. I'm not much of a Wiki kinda guy but that's because I'm not much of a GTD kinda guy either. Don't misunderstand me I love the idea it's just that I don't generally keep up with it. One of the issues I've always had is the overhead involved in setting up a site to host the Wiki, dealing with access etc... Well TiddlyWiki has a neat approach to the whole issue, just take it with you which they make possible by creating an entire low budget Wiki engine in a single HTML file. It takes a few minutes to "get it" but once I did, I went ahead and set my self up a Wiki on my portable drive and think there might actually be a good chance that I'll use it. It's a great replacement for the dozens of little TODO.txt files I have laying around everywhere.
GENi is a new "Web 2.0" styled genealogy site. The interface is nice and very easy to use. I'm not big into these things but I have to say that this is so easy to use that I built a sizeable family tree in just a few minutes without even realizing it. It's clean an crisp although it's still pretty young. If this matures to include an API, allow trees to be "grafted", additional information to be gathered/associated with each node and gets some momentum from the community then things could really get interesting.
Another interesting direction for the GENi interface would be to use a similar tactic to manage FoaF networks in all of their forms. Of course this all takes us back to the problem of allowing the source of record to be managed by the actual source. Maybe this kind of interface could be used to break the mold of the current stock of plain Jane CRM systems as well. Converting a standard address list into a networked graph would allow a certain amount of processing to occur across the graph and that could provide one hell of an edge on the competition.... Then again, maybe I just have too many ideas centered around graph theory on my mind right now ;-}
