As location is turning out to be the next big thing online, it’s imperative that new apps will emerge in order to make use of this opportunity. The Hotlist is one of them, and I’d say a pretty useful one. It aggregates location-specific data from various sites (primarily Facebook) and shows the hot events around you on a map. You can easily check the events your Facebook friends are attending and the kind of crowd the event is likely to attract.

The app has also started using the recently launched Facebook Places to deliver more accurate information. For each event, you can check various details like reviews on Twitter and Yelp, and much more.
You will require a Facebook account to use this tool.
