LOL on the typing. I know all about that!
I just think it's best online to not get involved in a lot of the usual 'good hand', 'well done', etc. I find that some people just don't want to interact and if a couple of people at the table absolutely insist on interaction after a hand, they get chapped if others don't respond. Sometimes, you just don't want to talk! And I don't think you should have to either.
