So let me tell you a secret: Joost is boring to me.
I am one of the few beta testers. Yesterday I tried Joost again, switched through the channels and nearly nothing has changed since I tried it weeks ago. The channels are presenting only clips that already would have bored me on MTV: fun sports, Paris Hilton, mainstream music and the like.
That's not what I expected from a new form of television, which has the capability to present unlimited tv content so that there also should be something for me. I am quite amazed how smoothly Joost works on a lame DSL internet connection. So the technology behind it must be great. But the content must still be a placeholder. At least I hope so and I imagine why it is like this: They had former MTV people in their team when Joost was still in stealth mode and it's name was the Venice Project.
Nevertheless my friends are very keen on Joost and would like to try it themselves. So they ask me for invites. But sorry, I can't. They just don't let me invite you:
We're gradually expanding our network, and we'd like you to invite new people to come and join in.
Every once in a while you will receive tokens, enabling you to send invitations to friends, family or anyone else who you think will enjoy watching internet TV. Each invitation will cost you one token, regardless of whether your invitation has been accepted or refused.
Number of invitations you can send: 0
It seems that I am not the only one who can't invite, since others are also complaining in Joost's beta tester forum. No tokens, no invites.
