That's exactly the 'interesting side effect' I was referring to. I try to compensate by 1) not interacting socially with most people at work, especially people who work for me (so there's not an in/out group) and 2) trying to make a conscious effort to have a good professional relationship with people I work with, as far as possible without it becoming social. IE I will have business discussions with everyone, but leave the personal anecdotes and social interaction at home. That leaves me being viewed as a little bit aloof and anti-social, which could be a problem except that I've always been viewed that way anyway so it comes naturally. But yeah, there are traps on both ends of that spectrum and littered through the middle and no clear cut solution.
