I find this site really useful, because it has events that I sometimes may never had known about, and because I can easily get RSS updates of events in my city(Houston) as well as other cities I go to when I'm traveling. It has a nice clean, simple and intuitive layout that's so easy to navigate. The other thing I like is that I don't have to sign up for it, and it's free. I think the real value is for people that have public events, but don't an advertising budget. You can promote all your events including multiple-day events, and you can customize how how the events display. My overall impression is positive.
