My first app: wat2do, a daily map of events in SF

Feedback/suggestions/bug reports are totally welcome.
I did something similar a while back using Google Maps for finding stuff to do in San Diego: http://sdhangouts.com
Are you planning on adding any ability for people to add their own events directly to the map?
For what it's worth, I also look at this: http://squidlist.com/ from time to time for events around the bay area.
