Thanks to a heads-up from Brad, I took a look at the newly updated MIX08 website. I like the site design - simple and easy to navigate, but with some nice effects.
MIX08 will be at The Venetian in Las Vegas on March 5-7 and registration is now open. Keynotes from Ballmer and Guthrie, solid sessions, party at Tao, and of course Vegas itself == good conference.
It's usually a pretty tough event for Microsoft staff to attend, but I'll keep my fingers crossed...
