Yeah but I'm surprised someone would know this if they're not from the region, and also why would that make them put it in the same group as e.g. Polish. Plus I feel like it's as different from Serbo-Croatian as Macedonian is, so why not single them out as well. I mean I know I'm nitpicking and this is just a funny map, but I'm still very intrigued at why someone decided to randomly do that.
