Threre are the whiners, true.
There are the ecomplainers as well.
Ther are the legitimates who have a beef, and want to 'duke it out' with the rest, or someone in particular...
There are those who don't like the right / most common answer, and are looking for the schmuzz who'll blindly agree..
There's the ones who feel strongly enough to write their opinion..
There are one who can't put a thought toghether, then type it out...
There are ones who type phonetically...
there are those who are dyslexic, and have never been good with spelling (me..) let alone have 'typists' fingures..
Some jsut want to be heard.. and will say anything

But I'll agree that ther are a few who poke & provoke..
