Serbia: Where is Facebook's Belgrade?

According to Belgrade 2.0, Serbia's capital has mysteriously disappeared from Facebook ^[1]: “Anyway, there are couple ^[2] of groups ^[3] now fighting to get Serbian cities back on the list of hometowns, since about 70 thousand Serbs that are already on Facebook just lost that option. Unfortunately, the protesters are not being very constructive, mostly crying over our fate and cursing the Americans. Although, one good suggestion came from a user who suggested that we find the Facebook embassy in Belgrade and burn it. :)”
