I learned about:
Gliffy, a tool for making diagrams on the web (Visio for the Web).
SwapThing, a swap meet that does matchmaking for swappers
tracking shot, takes a bunch of photos and sound track and generates a movie that matches the music.
Liftopia, selling lift tickets online the way Expedia sells hotel rooms online.
and I met several other interesting people. The best part was that none of these people worked at Google. I have nothing against Googlers, I just want to see who else exists in the world down here.
