To my fellow artists: don't wait for an audience. Just go ahead and keep posting stuff. No, seriously.
Yes, I know there seems to be no point in posting if you don't get any business or favorites or comments or views. To be completely honest (and this is just my not-so-humble opinion), social media has trained us to anticipate and relish that thumbs-up 'like' signal, like a kind of Pavlovian conditioning. I've experienced this plenty of times, and I know all about the cripplingly hollow feeling that comes with uploading something you worked hard on and not getting any comments on it, or opening commission slots and not getting any nibbles. I know ALL about that.
Please, please do not predicate your self-esteem on your success and/or popularity in the fandom. Do not judge your art based on how much attention or business it gets you. Engaging in these common but forgivable mistakes will only make it tougher for you to even approach the drawing board in the first place, because of the seeming responsibility every single brushstroke takes on. If nobody commissions you here, then use whatever other avenues you can, like Tumblr or Twitter. Revise your marketing strategy, adjust things based on trends and audience demographics if you must, but DO NOT judge your success -- or a site's success -- by an external scoreboard like comments or favorites. Do not abandon a place solely because you're getting more kudos somewhere else. The rewards are nowhere near as obvious or instantaneous, but they are rewards nonetheless -- and in the long run they WILL pay off.
Whenever Furaffinity comes back, it's going to get a little bit quieter around here again, and people will have to decide how they want to proceed. Nobody can guarantee whether or not Weasyl will succeed in the long run. However, it is very possible to guarantee Weasyl's failure. If no one uploads, then eventually Weasyl will join Yerf, Artspots, Nabyn, and ArtVark in the wastebasket. If you want this site to have a chance to succeed, then forget about rewards and just keep posting.
