Let's be honest.
I know a lot of people absolutely love word minimums for their RPs, but this isn't really to discuss that. Not directly, at least. Right now we're discussing a mixture of quality and quantity.
You see, for some people like me, I can write a decent short post, but when I'm forced to pump out longer posts, the quality decreases exponentially. So now I'm asking for your opinion: would you rather see someone post a great "short" post or a mediocre "long" one? Does the short post pack more punch or do you find it easier to work with a long one because it perhaps gives you more information with which you can work?
