Every time I see a "realtime" thread, one moronic wannabe just shows up trying to make the OP feel as stupid as possible.
It is incredibly obvious that the OP is a beginner, and doesn't need actual realtime input.
Correcting misconceptions of a beginner is a very important step, especially because such misconceptions can make researching your own answer extremely difficult because the keywords you use are not the keywords which will be helpful. I did not see what tonemgub wrote as something to make someone feel stupid.
I just feel there are other ways to explain the difference.
I won't deny the fact that I'm overreacting, but it's just that I think beginners do not need to know things like this at the stage they're in.
They will probably not understand what you are talking about with the knowledge they have, so they will assume it's hard to check for input or use a timer.
You have to realise that people do not react to information the same way you do. Just because you understand what a post means, does not mean the relevant OP will understand.
