Revver's got a great toolsuite for creators and viewers, and to my eye, the videos look better than YouTube's or Google Videos, and a great collection of social gizmos to help you find the best stuff on the site. The extensive API invites you to remix the site to your heart's content -- unsurprising, given that one of Revver's founders is Ian Clarke, the co-creator of Freenet.
With the 1.0 launch, Revver substantially updates the creator tools, API support, and adds a Flash player and playlists. They've also ironed out a lot of bugs and added a ton of fit-and-finish to the service. This is good stuff.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
