I feel like a rant. I may even look like a rant

Is it just me, or is the Internet killing the English language? I'm sure the schools are still teaching English grammar but yet half the posts and blogs on the Internet are hard to read with all the mis-spellings.

"Could of" instead of "Could have". I mean the shortened version is could've as in the have is shortened to 've. How could that ever be "could of" ?

"theyre ipod" instead of "their ipod". SCREAM! This one even appears in a book I'm reading at the moment.

Not to mention all the "c u" "u 2" and other text talk.

Am I just getting old or does it annoy anyone else?
