Why do cs majors and programmers tend to be socially awkward?

Actually, since you have above average social skills, you have the potential to go far. A really EXCELLENT programmer has absolutely no career options. If you are a genius at programming, you will make good money...but no company is ever going to give you any other job, except for programming. On the other hand, if you are familiar with programming and you have great social skills, there's a pretty good chance that you'll be promoted to manage projects.
