I just found this site that is using Facebook in the most cunning way to reach large audiences for a site of high demand on Facebook. The site is http://www.peacefire.org/circumventor/ and they offer a way to access Facebook from school (It is blocked at most high schools.). Their methods can be applied to any other site that is popular with the Facebook demographic. Facebook makes it very hard to spam users. You can only send messages to all members in groups of less than 1,000. Well, this site got around it by starting an event instead of a group. Their event is here for refference: http://hs.facebook.com/event.php?eid=7373257306&ref=nf They have the ability to send messages to over 30,000 people at once, and the number is growing daily. Events like this spread virally.
