more updates and ramblings in Off Topic
There could be several answers as to why we do not get these posts:
I doubt number four is the source of the problem.
While its charter isn't explicit, BYOND Volunteers was supposed to help establish a group of "real BYOND game developers" which would help dictate viable content. That is, give newer and lesser experienced developers a taste of what is expected in the community. However, as you probably have noticed, this group is largely inactive... this is not a good thing. (see Zan: a good game that has faded into obscurity despite all attempts).
I think the entire BYOND Volunteers idea isn't going to generate activity without more notability. Right now, BYOND Volunteer posts are quite unnoticeable. In this sense, Forum_account's idea is a step in the right direction, and we should also ask what other ways are there to promote and advertise efforts such as BYOND Volunteers.
But it's one of the few sources of the problem that can be addressed. We can't force people to make better games, but we can change the environment to better foster game development activity.
It's not that developers are deciding "I'm not going to work on a game because, when I post about it, it'll be chased off the front page by a bunch of nonsense posts." What's happening is that passively, because most people are making "check out my new base icon" types of posts, developers are feeling satisfied with their work long before it's complete so there's no motivation to finish it.
It's a rather large (and difficult to prove) assumption to say that developers feel satisfied with their project because they see low quality blog posts and that's why they don't complete it. What about people like Geldonyetich who strive to create content and yet simply lose interest?
My opinion is that eventually developers just lose hold of the incentive they had for creating the game
