Looks like the good folks over at 37signals like our placeholder page for Brightkite 
From their site:
Came across this ‘we’ll let you know when it launches’ screen (at brightkite), which is a little bit out of the ordinary. It lets you get notified not only via email, but also via IM and SMS. Pretty neat, given that the product they’re promoting is about notifications.
As avid fans of their stuff (RoR, Basecamp, Campfire, Getting Real, etc.), we’re quite honored by this mention. Thank You, Matt!
uh, you linked to bightkite.com. ooh, that’d be a good website too. bightmykite.com!
Good catch…fixed
