During preparation of a Main posting on games which got longer and longer I wondered what a typical size of a Main posting might be. So I took a sample of the 12 most recent articles (not including status postings).
For these I got an average of 3000 words and a standard deviation of 2500 words. The camel has two humps though. 9 postings were below 3000 and three were above 6000 (by lukeprog and EY).
I was urged to write a lukeprog-style Main posting on parenting (I may) so I take that to mean that postings with more than 6000 words are OK - if they have a high quality.
