I have considered this question thoughtfully and I do not think the author of XKCD is on the spectrum. Brilliant, yes, with a great understanding of mathematical and programming concepts. But when I've read his "blag" blog iand his comics, it is clear to me that he is socially quite capable. (Lots of posts about sex, relationships, parties). A lot of us relate to his comic- both in subject matter and presentation- but maybe he just really knows human nature and social interaction rules just as well as he knows coding and computers. And I really thought for sure he was NT when I saw the pic of him after he installed one of those things full of plastic balls that you jump into in the office, and all the people in the office sitting in it together, having fun.
Now that I just wrote that down, it seems like a silly answer, but you asked.
