So, I was blissfully unaware of this for a year since some kind soul gifted me a premium membership, but at this point, dA has become borderline unusable for me without one--it loads slow as molasses and gives up halfway through serving up thumbnails. I assume it's been like this all along for unsubbed visitors, which is unacceptable. I do not want people to have to deal with this if they just want to look at my stuff.
If anyone has suggestions re: similar gallery-style art sites that are less of a shitshow, I'd love to hear them. In the meantime, if you happen to use tumblr, you can follow either my finished-works-only one (contains the same things I post to dA) or my sketchblog, which covers everything I do. I will not be posting new pieces on dA from here on out.
