Well if you're shy enough it will stymie your social life. Also it has nothing to do with introversion.

But I think the OP's point is that "introvert" now means anyone who could be either, shy, or socially anxious, or any number of other things.

I remember not that long ago the on-line geeky community embraced Asperger syndrome as an excuse for lacking social skills, or being socially anxious, or forever alone, etc. People who clearly did not have it claimed they had a "light" version of it. Other people called them on it, fortunately that meme did not sick.

But the all my social awkwardness is due to me being an introvert (when in fact you could very well be an social super awkward extrovert) meme is sticking.

That's too bad for those who are not socially awkward at all, but are introverts. But oh well. We just need to invent a new term which will not be co-opted by every shy and socially rough extrovert who thinks she's an introvert because he doesn't have enough friends or enough recognition at work.
