Holla!
I guess whether or not you read them all and change your answer accordingly depends on the kind of person you are. Personally, I try to read all the responses before posting, but sometimes the thread is so long I don't have time. I've been trying to read the Random Chat one for like three days, and every time I get back to it there are 16 more pages!
If it's an opinion-type post, then it makes sense to read through it all first if you can. Sometimes someone says what you were thinking, and sometimes you see things that change or at least make you reconsider your opinion.
I think it's ultimately up to you what you post and when and for what reason. As for me (and Cartman), I do what I want![]()
