Certainly agree with that. In my experience posting on various Philosophy forums and from when I was a Philosophy undergrad:

Yes, it's difficult to write with clarity, I certainly wish I was better at it. But a bigger problem is a lot of Philosophy student types write in complex, superfluous and obfuscating prose to try and show off/sound clever. It's like there's some unwritten rule that the more it makes the reader frown and squint, the more profound the content. I'm reasonably convinced it's the opposite that's true. I'm not sure if anyone's with me on this, but this tendency annoys the crap out of me, since it's seems so anathema to the whole purpose of Philosophical enquiry.
