I never had much luck with Facebook groups. They all seem to just lie there and do nothing- really not a great feeling when clients are trying to use them.

The temptation is to put a wall around Facebook groups and bar myself from going there again. However, I started to notice to some groups did work- generally those formed around an event or a cause. So I set up a group (http://www.facebook.com/group.php) that is both, focused on my participation in the Pan Mass Challenge charity bike ride this summer. After one day I already had 50 members and started receiving sponsorship donations.

Passion and a call to action- not just an affinity- are key here. Have you had something you thought was useless until you took a different approach? Tell me your stories!
