SxSW 2010: Austin is now the Thunderdome

The rumor at SXSW is that attendance for Interactive badges is up by 40% from last year, which is pretty amazing when you consider that the 2009 attendance was 10,741. So the amount of people decending on Austin, TX to see the next Twitter or Foursquare make an appearance is around 15,000. It’s crazy to think that Foursquare just debuted last year and now it is the most talked about product so far at this year’s event (granted, things are just getting started.) Speaking of Foursquare, we’ll be covering their SXSW news, as well as that of what we consider to be their main competitor, Gowalla, in the next few days.

It also looks like some of the big names we’ve seen in the past are back in 2010 to take part in the festivities. I saw that Pepsi, Microsoft and Aol were still building their booths this morning.
