On a day where I'm anxious or irritable, I don't have to talk to anyone if I don't want to.

Exactly!

So much easier.

Although for me the main benefit is, I think, the ability to select for actual things in common,

I cannot tell you the things I have brought up thinking someone is going to know or understand...only to find out that I was wrong and then having to go through seeing them face to face after *headpalm*
