Define "Correct English"
Writing skills are not set in stone and will constantly evolve with time. You can see a huge difference in the style of writing in books written in the 1800's to books written in the mid 1900's and i'm sure 60yr old scholars of the late 1800's had the same thoughts you do now to the current styles.
You can hang on to how you were taught as long as you like but lets face it, its old hat to the teeny boppers of today![]()
There's a difference though, yes, English changes, but when you have a variety of spellings for each and evry word, something's gone horribly wrong. This is what's happening with text speak essentially. It wouldn't be bad if English evolved into text speak eventually, as long as we all spoke pretty much the same text speak.
