A while back, I created a map on Platial called Great Places to Sail. It's a Google-like map where people can put their favorite places to sail, add pictures, links, comments, etc. A number of bloggers like Edward from EVK 4 and Chris from Bluewater added their favorite places. There are now over 140 places on the map.
Last weekend, in a sad obsessive moment, I turned it into a Facebook application. If you are on Facebook, I would love your feedback. If you like it, please add it to your profile. You can check it out here.
By the way, I am not alone in being a total geek saddo. LiveSailDie, created a Facebook app too.
