It does bother me, to some extent, to see what technology has done to the English language. While it frustrates me to see how bastardized English is becoming, I am also aware that people from different backgrounds may not have had the same education that I received, nor the same enthusiasm for wanting to keep a language pure. I also recognize that because English is such a widespread language, it is going to change over time. But if we abandon the rules altogether, what are we left with?
To be honest, English has been a bastardised language for God only knows how long. It's a hodgepodge of Anglo Saxon, Latin, French and just about every other language it's come into contact with over the centuries, which is why it pronunciation, spelling and grammar are so confusing and full of exceptions. It's going to carry on evolving in the same way regardless of what people want it to do.
I'm all for proper use of grammar. It's there for a reason: clarity and precision. I'll quite happily read posts which have been written with poor grammar if they've got a point worth reading, but I must admit some of them are heavy going. The things that really bug me are: not writing in sentences, mis-use of apostrophes and mixing up homonyms. I work with and for people who know how to use English correctly and it's just so much easier to understand what they mean when they write.
I'm not going to pull anyone up for poor use of English but I'm certainly less likely to read what they've written if I have to rewrite it to understand what they're trying to say.
