We may not have the iTunes Music Store or the Kindle here yet, but at least we've got Foursquare.

Yes, the mega-popular-with-the-geeks social networking application has just announced a 50-city global addition to its network with Dubai chosen as one of the lucky cities.

Foursquare is a bit tough to describe, but it's basically a real life social network tied to a gaming business model. For example, you get certain credits or titles associated with yourself everytime you visit a certain area (the Dubai Mall, for example). Keep visiting the same place and you'll become the "Mayor" of the Dubai Mall (within the confines of Foursquare, of course). It is (somewhat annoyingly) quite big with Twitter users.

In any case, it should be available to download through the iTunes App Store and the Android Market (if you've got one of those devices). No idea if the program works in Abu Dhabi or any other emirate, but given that the founder of the company expects to make Foursquare available everywhere, more UAE and Middle Eastern cities are likely on the way.
