It's nice to see some support on this thread for standardized English. I'd expected more attacks against it (which tend to be generated most vigorously---naturally---by those who can't spell, apply standard grammatical rules, etc.).
Of course, the problems with today's state of written English go far beyond spelling and grammar and penetrate to the very meaning of our writing. Logic and reasoning are increasingly tilted into an abyss of confusion, even nonsense. In the worst cases, people may end up saying the exact opposite of what they mean!
And then there's so much redundancy and "padding"---so many wasted words that add little or nothing.
In longer pieces, organization is often hopeless, with section or chapter headings that bear little relation to the material that follows them.
I spent 27 years as a professional editor (for several scientific journals whose names you'd recognize) and have literally seen it all. And I've watched the deterioration progress steadily. It's frightening how many M.D.s and Ph.D.s out there can barely translate their thoughts into clear written words. My job as an editor was often to figure out what they meant and then say it for them.
Of course, THEY got all the credit.
One of the difficulties, on the editorial side, is that anyone can call himself an editor and set himself up in that business. As a result, there are plenty of bad editors out there alongside the bad writers. In an effort to address this problem, an organization called the Board of Editors in the Life Sciences established a certification program for editors that is now globally recognized:

In general, I think the quality of the writing on PO.com is remarkably good, which is greatly to the credit of its members. People seem to make an effort to compose their posts well, and this makes a real difference in what we're all trying to achieve here.
