I was an English major so of course I can appreciate good punctuation and spelieengSeriously... I guess many of us have our own unique way of speaking, and some may want that to translate to the written word.
My brother, who just turned 46, is new to computers and e-mail and all that. He doesn't type too well. But he ain't heavy, so I don't hold it agin him. ;-)
Also I think there is a difference between formal and informal speech/writing, and that there is a time and place for each.
