If you haven't heard, joost is now offering unlimited invitations to the current beta users. Previously, they were only limited to the hand-full of beta users and anyone who wanted to join had to receive limited invitations from current joost beta testers just like that of gmail during it's initial test phase. As of today, joost have removed limitation to amount of invitation that can be given out by current beta testers.
It is like YouTube but with more legal television contents as well as better resolution. According to Joost:
Joost is a new way of watching TV on the internet. With Joost, you get all the things you love about TV, including a high-quality full-screen picture, hundreds of full-length shows and easy channel-flipping.
I am fortunate enough to get myself an invitation and have been very pleased with quality of the television that I can see. If you would like to join and require an invitation, please leave me a comment with your email address. I'll send you an invitation as soon as I can.
