Mile wide, inch deep.<p>Or more like a millimeter.  The problem in bigger cultural hubs is that people already know where to find event listings -- there are just too damn many.  What they want to find is that narrow stream of events that match their <i>taste</i>.  The key to that (if there is one) is probably a recommendation service similar to what YouTube offers, combined with social graph search.  Which of course requires lots of data.  Which is of course hard to get, unless you already have it.  Which is why this problem is so dang hard.<p>But apart from a recommender service... an app which robustly shows events <i>nearby</i> could potentially be quite useful (often people don&#x27;t particularly crave to do anything exciting on a given night -- they just want to go somewhere nearby with friends, and find out quickly whether the place they&#x27;re going is hosting something they might like... or something they&#x27;d rather avoid).  But I&#x27;m not sure your app does that well enough yet (at least after plugging in a certain popular but not overcrowded neighborhood in my city, then getting flooded with events very much in the center, and miles away).
