Socialight

How weird. I don't even remember registering for this, but it looks rather neat nevertheless:

Hello there, friends!

As an early holiday gift, we're inviting you - our lovely beta test users - to run wild on the new version of Socialight. During the past few months, we've explored the dreams we have for Socialight and the suggestions and comments you've made and have done a pretty comprehensive overhaul that we're quite excited about. Here's a quick overview of some of the changes you'll see at http://socialight.com

* a brand new logo and web site design, and even a new name for our place-based messages - Sticky Notes. StickyShadows, RIP. Word.

* more ways to access Socialight while mobile - new mobile web (WAP) and text messaging (SMS) interfaces let you find and create Sticky Notes anytime, anywhere. http://socialight.com/help/mobile
