As anticipated, location-sharing services were the talk of the town in Austin as engineers and entrepreneurs convened for the South by Southwest Interactive festival.
“Location, location location,” Playfish chief operating officer Sebastien de Halleux told me when I caught up with him. “It’s a big theme for the web at this stage.”
