Facebook, if you use it right, is more then just a time sink. Rochester has almost 30 facebook groups focused on swapping goods, and the two largest have thousands of members!
The first, Rochester Area Mom Swap, has over four thousand members. They require you to fill out a simple form to join the group, but once you do you get access to four thousand moms worth of childcare products and expertise.
The second, Rochester Pass It On is even bigger, with over five thousand members. To join the group, you just need to have a friend who is already a member. This keeps the growth to a reasonable pace. In RPIO you can give or request just about anything for free!
