Keep an eye on FourWhere -- a deceptively simple "mashup" of comments and venues from location-based social network Foursquare on Google Maps. With it, users can search by city and neighborhood,
and see recent "tips" from people who've checked into various nearby restaurants, bars, stores, and offices. "It does the job," writes TechCrunch -- despite the fact that it requires users to
right-click to see comments or venues, rather than simply having a menu on the side.
"I'm kind of surprised Foursquare doesn't offer the exact same functionality, but that's what APIs are for," says TechCrunch's Erick Schonfeld. FourWhere was apparently created as a demo app for SXSW by social media analytics firm Sysomos, which plans to add more data from services like Yelp, Twitter, and Gowalla going forward.
