Should i read all the posts before i make mine?

If there are only a few replies before mine, I'll read them all. However, if there have been more a page or two of replies I won't read them all unless I find the topic really interesting. I don't usually only read the original post even if there are a lot of replies. Instead I'll read a few random replies just to get an idea of where the discussion is going and what ground has been covered. Maybe I just think too much, but that's how I do it.

Just read the discussion and post your reply ... simple ...

well if too long i never read all, only subject, the pont of topic and the question. but if short post i will read all.

No one can do that and it is humanly impossible to do that so u can just skim thro the most interesting ones and can start ur discussion and the same goes with replies as well
