You must first recognise that play by post roleplaying on a forum such as this and many others such as RPNation and Iwaku are inherently mercurial and chaotic in nature. Posters are not electronic robots that you encounter on the wild wastes of the internet. They are people. We have made this grave for ourselves whereby we value some abstract concept of literary quality as the marker of a good RP. There are multiple factors that make a good RP and focusing inherently on one single factor does nothing good for you. 

Blaming them for the failure of your RP is about as useful as blaming water for being wet. It’s redundant at best.

Ultimately, I would encourage everyone that the best way to get more out of this hobby is to learn and adapt. Staying stagnant with one single routine and one single fandom and trying to get people to fit within a mold that you have crafted isn’t the best approach. Join other RPs. Learn from other successful posters. Try to have fun. Learn from your failures. Failure is a teacher whose lessons are not always obvious at first but it’s up to you whether or not to take those lessons to heart.
