An interesting thing is that with the NSFW art turned off, you also get much less refrigerator art. I have a variety of theories about why this might be the case, but it goes along with my general observation about "fandom" art (whether furry, sf/fantasy, anime, or what-have-you): that "adult" art, at least in fandom, just plain tends to be weaker art. It's not universally true — I have seen some beautiful pieces of art that were only just barely safe for home. But the general trend is for artists to use the shock/titillation/sheer WTFery of an "adult piece" to sell it, allowing themselves to be lazy on the actual execution of the piece, which is one of the reasons I don't do it.
When a piece doesn't have that crutch to hold it up, on the other hand, the artist has to put more effort into making it stand on its own merits — which, if you do it enough, will make you a better artist, giving you the confidence to do more accomplished pieces. Win/win!
Anyway, as I've commented before, FurAffinity is where the eyeballs are; as fond as I am of ArtSpots, and as "big" as DeviantArt is, I've received more comments and feedback on the pieces I posted to FA over the past week, than from the other two sites combined for the past year. I've also been finding some new artists to watch, which is always a happy occasion. I am one of those creative types who feeds on the energy of being around other creative types and feeling like I'm in a vibrant community, where I can be inspired and hopefully inspire others in turn. And with FA providing that, the least I can do is be more supportive of the place. :)
It still has its issues, of course ... and I'm not going to abandon my other galleries by any means. But I am at least going to be more positive about FA.
