Posting about how many Joost invites you have left to offer makes you cool.
Brought to you by the same guys who started Skype and Kazaa, Joost lets you stream TV to your screen, and they’ve just started letting users send out Gmail-style invites. We just downloaded it, and we’ll be watching old episodes of Stella for the rest of the day. (By the way, we’ve got 870 invites left, so email if you’d like one. Ahem.)
