This is not new, yes, guys actually write like this. Its been happening at least 10 years and probably longer.
One time a buddy of mine gave me a floppy disk and said he had a letter to a chick on it. Disk wouldnt read. I managed to use some utility to recover the file. It was only about 3/4 of his letter but it worked.
The letter was a MESS. I told him that you are not supposed to write like you talk, especially when you talk like a fool most of the time.
I really dont think our highschools prepare kids for the outside world, especially when it comes to written communication. Folks will spend 8 hours a day twittering and facebooking and texting but they do NOT know how to communicate, they just think they do.
