If you want to participate and grab your name or your favorite nickname or Twitter Id — be prepared to login into your Facebook account tonight after (at) 9:01 PDT.  At that point you’ll get an automatic prompt to pick your new Facebook URL.

In practical terms this means it will be easier to share your Facebook page with your friends — you currently have a unique identifier for your account, but it’s hard to remember or share since it’s mostly numerics, mine is http://www.facebook.com/people/Dan-Perlman/533795967, not that I actually think of myself as 533595967.

Those of you not out here, set your alarm clocks.
