Well, do it yourself, you lazy bum! GigaOM and NewTeeVee are offering up self-invitations to the new Joost service that is taking the Intertubes by storm! I personally haven't played around with Joost that much, but from what I have done it is an alright service. Let's just hope they have added some servers to handle the load of beta users.
