I tried Google Wave and see great potential in collaboration. I also see Google Wave treading into Facebook’s territory not Twitter’s. Mashable has the best write-up thus far including a reference to Google Wave’s advance serarch commands. Robert Scoble discusses the overhype and sums up the problem I’m trying to get my head around "noise" and "I don’t know where to look".
I tried TinyChat which is a video chat service that promises to supplant Skype but the true potential is in the features included in the $14.95/mth price. The video quality is high. The features are well integrated into the user interface. I think this could be a lot of fun for synchronous chat but I question why use TinyChat instead of ustream.tv or Livestream.
I’ve also tried Twirl TV which looks a lot like Hulu for the networks. They also claim to only be letting the first 10,000 people in.
