I have, for about the first time ever in these forums, read a beautifully clear and typeset mathematical argument (by someone not a PhD). It also had the plus point of being correct. It is in the 'calculus and beyond' homework section, the thread about number theory (gcd and lcm). I'm evidently not alone in noticing this and feeling the necessity to comment on it. So, how about some recognition for people who write well? I don't necessarily mean an award like a little badge or even a big badge. I leave it to others to decide what 'reward' is applicable. But there should be some way to let the author know, apart from people replying with congratulations. Perhaps posts could be rateable (by homework experts or science experts or some other subset of people). If a poster gets enough plus points then that badge or whatever could be awarded.
