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 ‚Äì 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.
giving you new ways to find what you'd like to watch. You can search in
"traditional" ways ‚Äì by title or category ‚Äì 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 ‚Äì 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.
