I'm a normal guy, I just like reading other's opinions on matters that could also apply to me in the future or do apply to me now, I'm some sort of "hidden psychologist" so I like to analyze typical responses, analyze typical personalities and learn.
I also sometimes post to get opinions on matters I have no idea about (fe. cars).
I already got rid of discussion opinions so usually I just post mine but don't even want to get into discussion as it takes a lot of time and usually won't convince anybody anyway.
I think we all are normal people who have their own reasons to be here.
I also got used to posting and reading SH. It's entertaining.
There are nice people, there are idiots, there are class clowns etc. and it's just.. kinda fun.
Reading message boards is like a modern interactive magazine reading. You get knowledge and it's usually verified by more people than one idiot writing stupid articles
