Do you even read the previous responses before you spout your opinion on the topic?
I really don't like too, because it looses the spontaneous moment. Sometimes I do because I am not sure of the question and if I am responding accordingly. I usually will after I post. I like to post and not give a one sentence comment.
No. We are all entitled to our opinion.
My main problem is not reading posts fully beforehand.
I usually just address the poster first. I do scan comments after. Or when I have time.
