The other day I ran into a neat site while skimming the comment stream on Twitter. If you are a FourSquare User you can go to WeePlaces and generate a map based on all the locations where you have "Checked-In"
caught my attention earlier this year with all the hype at Inman in NYC but I had the Disney Marathon on my mind so I back-burnered the toy until after my trip. When I finally got around to loading it on my phone I recall some initial difficulty and failed on my first few Checkins but have been using it with some regularity since late January but the graphical features provided by WeePlaces.Com give you a nice overview of your travels.
The first day I sucessfully used FourSquare happens to be while attending WordCamp in Boston and within minutes of my checkin that was streamed to Twitter I was being asked questions for which I had no answers. Come to find out FourSquare awards "Badges" as an incentive to use the application and when I checked in at the NERD Center there was a "Swarm" of others also using FourSquare so I was awarded a badge.
Enjoy your Travels and log onto WeePlaces to see where you hang.
