I think you have way to many words on your home page. This is a service catering towards events so that is what I want to see when I first come to your site. If I wanted words I would look them on your site, the service should be able to speak for itself. Also, someone already mentioned it, but your domain and your name aren‘t very good. Stuff makes me think im about to be sold something. "How did you hear about this event?" "I found it on Stuff" doesn't work very well imo.
Being able to follow event creators and venues to learn about uncoming shows, and to follor my friends to know what events they are interested or going to.
Opt-in notifications based on GeoIP to find out "Hey, my neighbor is having a yard sale!" Obviously, having the option to create private events that don‘t notify the neighborhood as well.
Being able to post on the events to ask questions would also be an important feature.
Ill double check my notes later to see if there's anything I didnt mention.
