No, not like this. Not like this... please... no... uggagahaahawaahhh!!
I've seen writing like this, and I pass it by, it doesn't even get a second look. I always just assume that they are writing for remedial level readers. It's amazing how people complain about the "dumbing down" of society, but yet they will promote this practice. One has to wonder though how much of it is born out of social media and the various limited character counts they have. I remember telling students when I worked as a writing tutor that they couldn't use "BTW" "LOL" or any other text abbreviations in their college level papers and the looks I used to get.
