Mix07 Session Recordings Available
If, like me, you couldn't swing out to Las Vegas for Mix07 this time around, you can now access and download recordings of the keynotes, sessions, and panels. (Actually, even if you did attend Mix you'll want these since you can't attend every session while you're there!)
Head to http://sessions.visitmix.com.
