It's actually a lot of fun, and I've met some very interesting people. Diaspora already has most of the features described above, such as federation. I like how you can follow hashtags also, because it allows you to see comments from people you don't already know, and thus make new friends, something which I feel Facebook lacks. There are some strong devs still out there and waiting to jump in the game, I think D* will stay alive and eventually overtake Facebook.
