Intros are very important. They help others understand who you are and your frame of mind. Miscommunication in any social environment is rampant. Most of it is because the recipient does not fully understand the mind or character of the sender. I have an offbeat and facetious sense of humor . My friends all know when I'm being funny. But sometimes, a new person will look at me out of the side of their head and say "OK?". I am quick to point out that I made a joke and they catch on, but it's hard to do that on social media
