Concluding that something is not a learned skill because it comes easy to some is illogical. Human upbringing consist of a lot of social interaction (at least when done right), it is only fair that some people actually get good at it.

Anyway, I should probably have disclaimed my first comment more loudly: it's anecdotal. For me smalltalk is absolutely a learned skill. I used to suck at it, now I can get by, and it took a lot of conscious effort on my part. YMMV
