"Text speak is not any form of English and I think it is rude to subject strangers to it. Society as a whole is ever removing itself from basic manners with technology as an excuse."
I wasn't going to dignify the original post on this thread by commenting in any form. But I think you've hit the crux of the matter.
There was a time when written English (or French, German, whatever) was more formal than the spoken form. I believe this is still true of most languages. But, for some reason, English seems to be a glaring exception, in spite of spell-checking and even grammar-checking capabilities on our word processors.
Sadly, these days even scientific and technical writing is not spared this insult. Let us tolerate neither this, nor sloppy posture/footwork.
