One of the things I find most annoying is the use of abbreviated "text speak", where all the vowels seem to be left out. Even my wife succumbed to it when she finally worked out how to send text messages on her mobile 'phone. She only did it once with me though. I can't remember exactly what she wrote but my reply was equally nonsensical - I just sent a message back with all the vowels she had left out!
I do think, though, that the standard of written English has declined over the past few decades; and to think I spent a fair proportion of my working life correcting both the grammar and spelling of those that were better educated than I was.
