From what I understood HTTP 2.0 was designed by a committee that failed to come up with a usable standard. That is why everybody still uses HTTP 1. I thought that 2.0 was skipped over in favor of another standard but I could be wrong.
IETF is a rather chaotic process, probably the closest thing to "anti-committee" in the standards world. The working group chair, Mark Nottingham, is a pretty respected guy in the web world.
If you use Chrome or Firefox as a browser, you're probably already using SPDY as many larger servers (Google, Wordpress, Twitter, a bit of Facebook) support it.
