Joost Offers iPhone Video Viewing Plus Social Networking

Somebody must have asked "What would the mating of MySpace and YouTube look like?"  And Joost appears to be the answer:

"What's Joost? It's a way to watch videos – music, TV, movies and
more ‚Äì over the Internet. We could just call it a website … with
videos … but that's not the whole story.

We're
giving you new ways to find what you'd like to watch. You can search in
"traditional" ways – by title or category – or you can find suggestions
from other people on Joost. They may be your friends, or they may just
be people who have something in common with you – but either way, they
can direct you to great things to watch."

Anyway, it's a free download from iTunes with the usual caveats (iPod Touch/iPhone 2.1 software update).  Have at it.
