If you want to build an LBS app, but don’t want to collect/license the local data, consider TownMe‘s newly announced API. You give it location information it returns data. What data? Public data like census information, Tweets, stuff added to its website. Actually, the data is pretty weak in my opinion. Here are some demos of using the API.
