I'd just like to stand up for some people for a moment.
I am partically dyslexic and so I have trouble distinguishing between they're, there and their. I have to stop what I'm typing, look back and check it's the right one. This is rather annoying, and I tend not to do it until the very end. However sometimes I still don't notice it or do not have time to thoroughly check through. I appologise, but it is not always people being lazy or stupid.

But all the other stuff, big yeah. Needless abrv., Stupid spelling, OMGWTFLOL!!! and over use of the smiley...
