TechCrunch writes that Europe is a hotbed of mobile startups right now—even if we haven't heard of many of them over here in the sates.

"Appropriately enough, the Mobile 2.0 event which started in San Francisco is putting on a one-day international event tomorrow in Barcelona which focuses on mobile startups, dubbed Mobile 2.0 Europe."

TechCrunch blogger Mike Butcher is moderating a panel at the conference; the panel will consist of companies working with mobile proximity networking and Bluetooth sensing technologies, Android developers, a mobile social media network, and location-based discovery developers.

Some of this is clearly where mobile app development is heading, and should help to vault us past the overload of me-too social networking companies we've seen in the mobile space here in the U.S.
