I disagree with Perknose. Had I left, I would never have learned this wonderful new word, which I can now apply daily. So Perknose has even exemplified "rediculousosityness" for us.
But the goal of many here is some sort of "sloppy with style", which makes some of the rediculousosityness of that post sadly leave again.
I think good writing begins with good thinking, and that many of the complaints about writing are essentially complaints about the thinking or the clarity of that thinking as seen by the reader. More rediculousosityness? Well, you can find tons of bad thinking here, but you can also learn good thinking from seeing some bad thinking expressed and ripped apart. (Especially your own. /em ducks)
Based on my own experience, I recommend Philosophy. For two reasons -- for seeing and perhaps learning some good thinking, and for the exercise of language skills that accompanies this. Trying to express subtle concepts clearly is a good exercise for language skills. In this, writing is better than reading, because when you see really good, clear writing, you don't see the potential mess of concepts and languages that might have been there instead. When you go through an exercise of trying to improve that mess and express a subtle language-challenging thoughts, you can find that you've gained something.
