Some posts dont require more than a one liner. Most post make me have a thought and sometimes I sharr my thought. If a post makes me think ill usually engage more with it and make a longer response. Its great if you have the time but most people browse this site(and others) in a small section of time. Most people aren't going to read a wall of text but they will read a quick quip. It knowing your audience. Not to say we cant have meaningful discussions, just not every time.
