Evolving language

A friend and I were (showing our ages) complaining about the poor grammar and punctuation used by young people. She had received a job application from a degree student that was so poorly written it barely made sense.
At the moment I am writing copy for some mailshots and advertising that I’ll be sending out over the next few days. The purpose is to promote sales courses to a variety of businesses.
It’s made me think about words and phrases that may appeal to different generations. Are young people as put off by perfect grammar as I am by poor punctuation? Should I try using text speak?    Don’t think I can bring myself to do it……..
