It is a very handy way to have discussions. If you make a post with a single point, I do not need to take such measures. If you make one with multiple points that need to be addressed, this is a convenient manner to address them all without you or the audience having to figure out to WHAT I'm actually responding. It makes it slightly more difficult for people I'm debating to pretend I didn't say something with which they do not want to deal.You cannot converse correctly and you don't have the ability to learn simple things. It is straight forward. Do you honestly sit in a pub with a mate and when you reply, you start splitting up and repeating what he/she said with your silly comments between them? Bizarre.
