Just a quick photo of myself with John Heinsen (on left) and Brian Zisk (on right) from the Bluepulse party in San Francisco during CTIA 2007.
Bluepulse is a new purely mobile social network. Very simple to use (assuming you don’t have a crappy phone like what I’ve got) and extremely viral because for friends to see your messages they have to join. I wrote a full profile about them in my analyst job for The Guidewire Group.
