@Carlsberg If I can offer some advice that helped me back in the day, don't feel the need to compare your own posts to the posts of other people. Nine times out of ten (made up statistic!) this just leads to someone either forcing themselves to match up (and potentially losing steam in the process) or going for quantity over quality.
Granted I'm not the GM here, just a friendly Co, but quality should always be the focus over quantity. If you can put out a quality post that's, say, two paragraphs (and I don't even mean the silly 'five sentences is a paragraph' thing) then I'll always take that over someone who puts up six or seven paragraphs where half of it is just obvious filler.
Different standards for different folks, of course, but that's my two cents on the matter
