Interesting sites on Web 2.0

I checked out Upcoming, Arcaplay, Googlemaps, Peertrainer. These were both fun and useful sites to get into. I especially liked the Upcoming site because you can find out what events are happening in a community near you. Or, if you are planning to travel to city for business or fun, you can find out what events are taking place while you're there. On my next trips I will see what on Upcoming then plan my activities.
