I think there's potential there. But I can think of two big factors/features which should be considered ... and some heads-ups: 1. Location-aware mobile searching. I can't recall how many times I've been driving around with my wife on a Friday night wondering "what should we do tonight?" ... if you built a startup around this post/concept, I think it would be a big mistake not to put a lot of resources into an iPhone/smartphone app. Think of it like Yelp's iPhone app but for events. 2. Let event coordinators sell tickets to paid events from your site. Don't do ecommerce and take a transaction fee. Just let them plug-in PayPal/Google CO info and be done with it. You'll immediately have an advantage over sites that don't do this. Heads up for: - Craigslist. If you start scraping their sites, they will probably block you at some point. - Facebook. FB is growing rapidly as a place for events/RSVPs and it fits well within the "social graph" ... the latest FB iPhone app puts events front and center. Expect them to be a big competitor in this space. Other low-hanging fruit: - City/chamber websites. Every city or chamber of commerce website has an event calendar. You'll probably want to scrape those. - Community colleges, libraries, etc. have non-credit/weekend classes and workshops. If you had a way for them to sell tickets, it might be a nice draw. That's all I got for now ...
