With South by Southwest Interactive Conference beginning, there’s been a lot of talk about who will take the reign in location-based services and apps. With Twitter rolling out its new geotagged tweets and Facebook on the verge of allowing users to share their location, the spotlight and pressure seems to be on the likes of Gowalla and Foursquare. Both have rolled out some significant updates recently, but who will take the lead?

CNN thinks it will be Foursquare. I was interviewed for the article and had these thoughts:

“I think it’ll be a while before it really reaches a mass audience,” said Vadim Lavrusik, a tech journalist, social-media consultant and graduate student at Columbia University.

“For us techies, we sometimes tend to exaggerate how quickly these things are going to grow because everybody in our circles is using it. But that doesn’t mean the general public is using it.”

Still, he said many of the criticisms he’s heard about Foursquare are eerily similar to the ones he heard from people saying Twitter would never take off.

“People say, ‘Why would people want to know where I’m at? Will my friends actually come and join me if they’re on it?’ ” he said. “I say, ‘If they’re on it, yeah, they will.’ “

Would love to hear what you think?

Here’s an idea that Shane Snow and I have had for a site and I’ve been meaning to share it for quite some time. The basic idea is to solve a problem in location-based restaurant information apps and websites: fragmentation. The rough name we were throwing around was Socially Edible (sociallyedible.com).

Let’s create a one-stop shop that combines online restaurant reviews (Yelp), location-based social gaming (Foursquare), and online food ordering (SeamlessWeb), and sprinkle in some journalist-produced restaurant reviews to create a connected user experience for foodies.

Why not start with a specific location, say, New York. These features with the combination of social media and mobile technology would make it easier for New Yorkers to get food news and information on the go, as well as the ability to order from our site.

A person looking to get some information on a restaurant can not only read what a reporter has written, but also what website users are logging in to say. On top of that users can also see what the buzz is on social media (blogs, Twitter, Facebook, etc.) through trending topics as well as specialized social sentiment reports for each restaurant page (perhaps by using social media mining software?). In addition, users can explore new restaurants in their area by searching with their address or zipcode and browse through search results on a map or list.
