Of all the startups launching things at SXSW this year, the most closely watched may be Foursquare , since they're a company that got their beginning at the conference two years ago. And it's looking like they're not going to disappoint. A couple weeks ago they gave a hint of what they had cooking: " NEW APP + NEW BADGES + PARTIES + CONCERT + MOAR ”. Now we know a little bit more. As you can see on this page , the plan is to launch the Foursquare 3.0 app, host a party on Saturday night, host a concert on Monday night, and launch 18 new badges to earn during the conference. But there really is more.
