Some people usually scroll down and read before they even comment. I can usually tell when someone has taken my idea. It doesn't really bother me too much... it just shows that they generally agree with what I stated.
Not really. I know sometimes I forget to read the other opinions, and then I do read AFTER I posted and realize that my comment looks very similar to someone else's :/ They probably think I copied them on purpose or something, but I just either forget or am too lazy to read through everyone's opinion to avoid putting something similar. Damn my laziness and forgetfulness lol
