This past weekend was the Ann Arbor GiveCamp 2008. The idea is Geeks Giving Back. The GiveCamp organized a number of charities(15) and a number of developers (over a hundred signed up and 90ish showed - I don't have exact numbers). We showed up on Friday night at 5:00 and started work. At 3:00 on Sunday afternoon, we showed what we had accomplished. In many cases, the charities just needed a web site or a better web site. In some cases, they needed real programming work done.
