The length = quality thing is probably an artifact of journal rp's forefather known as ye olde 'literate multipara rp.'
In ancient history, making people write a lot of relatively grammatically correct prose was often one of the few ways to weed out the absolute dregs. It didn't make for high quality RP very often, but it was so much better than dealing with goku29342's I KAMAHAMEHAED AND KILLED U.
The downside is that it's so ingrained that it really damages the fun of roleplaying and generally degrades the quality, too.
