For anyone who's not come across George Orwell's essay 'Politics and The English Language', in which he railed against 'ugly and inaccurate' contemporary written English (this was in 1946, mind), it's well worth a read.
His main argument was that much political writing was used 'to make lies sound truthful and murder respectable, and to give an appearance of solidity to pure wind'. So... things don't change much there!
He goes on to give examples of poor writing, drawn from law, the Press, Whitehall, politicians, academics, pamphleteers... the usual suspects.
The bit of the essay I always try (and often fail) to keep in mind, though, are his 6 rules for good, clear writing. They're still relevant today:
1. Never use a metaphor, simile, or other figure of speech which you are used to seeing in print.
2. Never use a long word where a short one will do.
3. If it is possible to cut a word out, always cut it out.
4. Never use the passive where you can use the active.
5. Never use a foreign phrase, a scientific word, or a jargon word if you can think of an everyday English equivalent.
6. Break any of these rules sooner than say anything outright barbarous.
Being a grumpy old fart, I guess I'd only add:
7. Never use text-speak - even when you're texting.
You can read the whole essay here, if you want to. It's quite a laugh, despite the title.
