I'm only 23 and when I went to school yeah we used slang terms and swore a bit, but at least we were taught properly and I'd say I have a pretty good understanding and application of the English language as a result of that and also my parents always reading to me as a kid.
Now I've come to notice lately that I'm in a minority

For some bizarre reason my 10 year old sister has started using z's instead of s's - something I only noticed the other night while on MSN to her and which I will make sure gets sorted

I got a takeaway leaflet through today - "Rajas Kebabz" - "Try our nan kebabz the biggest and best". Ignoring the z's I won't even bother correcting the sentence.
It's not just small people, people my age and probably older on facebook etc just make STUPID errors - "If your happy and you no it clap your hands!!" - the girl who had that as her status is doing some sort of "higher education" course!
I don't expect everyone to use 100% correct English in their text nor do I expect them to speak in the Queen's English; I don't know whether it's a sign I'm getting old but I'm finding it hard to communicate with people sometimes these days

It really irritates me when people use lazy forms of the language, lazy enough that I actually have to read it several times to see what they're trying to say...
What's to blame, pure stupidity or complete ignorance?!
