Might as well give my two cents here with a number of points being made recently:
Regs being elitists and discouraging to other art posts? I don't feel any sort of diminishment of my stature as an occasional poster in comparison to the sheer volume of posts by the few regs left. To date, I've had about four maybe five regs give comments on the work I do in my personal thread and all were helpful (really didn't expect maficmelody to take one of his comment as far as a drawing showing shapes representations in a space based off of what I originally posted, but like I said it helped.)
Wanting more art out of the regs isn't something practical, in a way. For all we know they could be applying their talents to collabs that are not advertised in the forums as of yet. Another possibility is that they are in a slump as far as coming up with new ideas. Unless they're doing something based on a reference, it's kinda hard for them to pull something out of their ass and call it an inspiration worth drawing.
I see Fifty-50, Aigis, and flowers10 (just to name a few) pop up once in a while, and they blow the s*it I put my mark on off the planet in terms of quality every time. But unless they post their works as they progress to get feedback in the early stages, it's easily a couple weeks of steady work or more to turn out the kind of quality we typically see from any of the regs.
And Kuma (going off your post at 4:22pm EST): Despite the fact that I am responding to this, in my mind this useless dribble of an argument is an example of why some of the more seasoned regs disappeared. Arguing over how people apply themselves and in what capacity rather than post more yourself, doesn't matter if what you post is your own work for critique by others or a critique of someone else that looks to be trying to improve or is showcasing , doesn't help. If you want more than what is offered, lead by example instead of laying the groundwork and expecting people to pick up what you started.
Words are forever just that, they carry no weight if none are willing to act.
