I have one. I guess it wouldn’t hurt to link it (a ton of old stuff). It’s SUPER inactive.
My opinion on dA is that it was a great place to start for me (wistful flashbacks to my preteen days), and it was really my first art site and inspired me to draw a lot more. I don’t regret my time on deviantART. I connected with a lot of cool people there! (many of them have since moved to tumblr). I also enjoyed the art memes and collaborative activities, and the groups (when they started out).
However, in hindsight it was really hard to get exposure (REALLY hard) and the only way to find cool art was to look through what was popular or go deviant-hopping which was basically going through galleries of the friends of people I watched which gave me a pool of really similar styles. It was much more tedious to find stuff that inspired me. I think my style would have been fundamentally different and stagnant if I stuck with dA. It’s just so much easier to find a variety and abundance of art and inspiration on tumblr, and I think inspiration from other sources is what fundamentally drives my direction in art.
dA is a great place to host a cohesive gallery though. There are several people who have found success through dA. I just feel it’s much more difficult than tumblr. It’s also going out of style imo, and their commercial sector is terrible.
