Out of curiosity, have you ever signed up for a twitter account and used it for more then five minutes? Personally I saw very little value in it as well, until I used it for a little bit and added a few people to follow. If not, I'd recommend trying, and run a client like Tweetie.

As for Wave, I still have no idea what to actually do with it. I logged in a while back, invited someone else, then stopped using it. With no notifications outside wave when something changed, it's a pain to have to log in all the time to see nothing. I suppose both services need some sort of critical mass for it to work.
