OnStartups Group on Facebook
I have created a new group for the startup community on Facebook.
The group free, has open access and you can join immediately.
Access the group here: http://mit.facebook.com/group.php?gid=7521561140
Within the first few days of the group joining, we've already got over 200 members. Look forward to seeing you there. Should be a great place to meet other startup people online.
