To me, seems a shame to see the language we use go this way. Is this the accepted form of English of out next generation? Perhaps I'm one of those old fellows that is resistant to change; parallel to one long ago who was appalled to see an abbreviated 'is not'. - Scotty
It really depends on the medium one is using to communicate with. In ham radio when using morse code they use so many abbreviations that one normally needs to tape a sheet of paper on their wall to keep track, QSL?. So it's not suprizing that cell phone texting has created it's own version of abbrevations to save key strokes and time.
However I agree that if one is at a keyboard posting on this forum that one shouldn't be using text speak if they can help it. But perhaps sometimes people are posting and responding from their phones and pads, hard to know these days?
