Sam Sethi over at Vecosys seems to have gotten his hands on a beta invite of Joost.com, the lucky man, and is trying it out. He says on Twitter that the web TV service hooks up with third party apps like Gmail and integrates with RSS feeds too. Maybe RSS is going to change TV like it did the web? Inevitably.
Web video is too clunky for the living room right now but Joost will change all that. If you had Joost.com rigged up in your living room and you subscribed to a bunch of niche channels on YouTube and the like, straight away you've got the long tail of broadcasting.
Imagine being able to watch TV and chat about the program maybe with the cast of the program or with other viewers in the forum. For a more personal experience you can use the Jabber/GTalk plugin to start a IM or VoIP conversation. I was pleasantly surprised that the IM client was not Skype but was in fact XMPP based.
How much begging do I have to do before I get let into the private members' Joost club though? Too much.
