I went to both sites for the first time just now. I was instantly drawn into ticketstumbler with the events happening this weekend in my neighborhood front and center. My first reaction was to subscribe to the RSS feed (but I haven't found it yet, please add it!).
I can't use it - I'm in Canada. But I agree that an RSS feed of events results (like a feed for events happening in your area) would be a useful feature.
It looks like you guys are off to a great start. Good luck!
