iPhone/web: There are a whole host of places to get your questions answered online, but what if your question is specific to your location? Crowdbeacon answers questions with the help of your local community, and aggregated answers from other location-based services.

Say you've just moved and you're looking for a good place to get a cheap haircut, or you're on vacation and want to know where you can get some real southern-style barbecue. Crowdbeacon is a service focused around answering these sorts of questions: it links you to a specific community and crowdsources other Crowdbeacon users and businesses in that community to get good answers.

The problem with services like this is that they require a large userbase before it becomes useful. While Crowdbeacon does seem to have a usable amount of folks signed up (depending on what city you're in, of course), it circumvents this problem by also offering answers using other location-based sites like Yelp, Foursquare, and Twitter. Crowdbeacon still carves an interesting niche in the sea of other services, as it aims to answer more immediate questions ("what are some good concerts playing in the city tonight?"), since their iPhone app can alert nearby users to questions that match their interests, but it's really nice that they have the other service integration to fall back on.
