I think this is a really cool and usefull thing to have. Everyone should put themselves on the map and make sure you list what you sail. It's easy to do. Just click on add yourself, then fill in your name and zip code, say what you want, and attach a photo. That's it.
BTW, the new link is http://www.frappr.com/catsailor . Guess Google decided to keep this one. Cha-ching! Their stock probably went up another $30.00. It closed Friday at $358.17. Unbelievable for a company that doesn't sell anything.....
