I got the following from Joost yesterday: "We’d like to share some good news and celebrate the launch of the new Joost beta – Now For Friends. This means you can now invite as many friends as you want to try out Joost."
If you want one, leave your email addy in comments or email me at techbytes_invites at mac dot com and I’ll see that you’re taken care of.

Hello – nice to meet you today. Joost is quite interesting – though I think it’s a crap set-top (6 foot) user experience, it’s a relatively interesting PC (6 inch) experience.
Best
I would love it if you could send me an invite. Thank you.
I would like a Joost invite please. Thank you very much in advance!!
Could I get a Joost Invite please Thanks
