I checked out the Developer site of FourSquare and it seems that they launched a new API for FourSquare apps and the old API will be phased out starting August this year.

Since BarrioSquare was developed a while ago it's pretty straightforward to assume it uses the v1 API, which means the app will not work starting August 2011.

If I had the skills to develop an app I would honestly do so. But I studied economics and accounting, so I have no I idea how software engeneering works.

But I've seen that recently, using QML and Qt, a whole range of new and exciting apps have been developed, such as cuteTube-QML and Kasvopus...

Since FourSquare is very popular nowadays, I think it'd be GREAT if someone could develop a new application. It would make me, and the rest of 4SQ users so happy...
