While I don't fully agree with the parent of your reply, I think they're right about communication being a skill. I am an introvert myself, but I've learned not to let that get in the way of me communicating with my colleagues or friends.

Not speaking up in meetings doesn't mean they don't have this skill though. Some people (like me) don't like to add on-the-spot opinions on something, but prefer to go and mull it over, look into it etc before providing feedback. Doing it on the spot often leads to a lot of wasted time and overly long meetings. Meetings and other synchronous communications are, in my opinion, very wasteful and expensive.
