@loudthoughts,
Clarity is great. Some thought are just difficult, though. And sometimes difficult thoughts are expressed in a unnecessarily difficult style. Even in this case it's sometimes worth it.
Also, difficulty is relative. Sometimes we just "click" with a thinker. Is Richard Rorty difficult? To me he's clear. To others, whose temperaments are opposite, he's not so clear.
I stayed away from Hegel and Heidegger for a long time, because of their reputations. They came up to often in the works of other philosophers for me to continue to ignore them. It sucks to not know what is being talked about. No pain, no gain. It's always tempting to write off what we have not yet tackled. It flatters us.
