I think what you are looking for is what interests people.

Skills are not mutually exclusive but I suppose you are much more interested in technical stuff and to learn communication you have to become interested in other people.

I am also mostly interested in learning technical details of some software or system and not that much in what someone did with his time last weekend.

So what makes people better communicators is mostly that they are interested about other people and other people opinions and other people mood.

Yes, this is exactly what I'm getting at. In theory, those two are not mutually exclusive, but in practice they very much are due to personal preferences and that will shape what you become good at.

Of course, there are definitely people who excel at both, but they are outliers. Most will only get/want to excel in one of those two things.
