One of my favorite new sites is Groupable. I found out about them on Mashable. Basically, they put together sponsors with groups. From where I sit, I can think of about 10,000 ideas for both sides of that equation. Lucky for me, Groupable’s fabulous Gerrit Hall is just a phone call (or AIM) away and responds to all of my ideas with enthusiasm and follow up (if only the whole world could be like that…).
