I think pretty much any site that has a bad track record has this: FA, dA, YouTube. I think part of the reason these moves never stick are because no popular artists are making a permanent switch and in turn, bringing their fanbases with them. Sites like that are also the established platform for their genre, and the users probably don't want to leave because of the possibility they could become popular at any moment and the popular people don't want to risk losing all that traffic and income. "Protests" like these go in circles and it irritates me to no end.
I like this idea. When the forums were livelier, I loved participating in discussions. The only problems I foresee are the discussions being all the same people when the goal is to get others chiming in, and discussions can get heated regardless of the topic so a forum mod may have to keep an eye on it to stop arguments before they grow big enough to warrant locking the thread.I'm not sure what to suggest other than maybe the staff itself visibly encouraging discussions among the users. On my FA page, I specifically tried to encourage discussion about sexuality and kinks (not in a "Ooh, so sexy" way but in a more psychological "Why does this do it for you?" or "Here's why this image is effective" way), but getting people to actually talk, YOUNG people especially, my lovely peers who grew up in an age where conversations were limited to 140 characters, can be like pulling teeth. But maybe the staff could post something here and there to promote random discussion. Probably nothing too heated, like politics.
Weasyl's staff are a small team, something like this may be too time-consuming to be purely staff-run. Maybe normal users chosen to be on a board of judges would work, but to prevent bias staff would have to pick people with a wide variety of tastes (like one judge that likes digital drawings, one that likes traditional, one for carving, one for sewn works, etc). They would also have to write up rules for the judges to follow. There will be people that cry favoritism if they aren't chosen, but those kinds of people are everywhere and I don't think that can be avoided.For the sake of getting some lesser artists off the ground they could maybe do some kind of "weekly staff picks" thing where they just show off a drawing they like or want to spotlight for one reason or another that might be from somebody whose not especially well known. Or maybe they could do some kind of monthly or weekly contest regarding art and try not to pick the same winner twice (otherwise we all know it'd be he same few people).
