I'm not a massive fan of Facebook either, but setting up a page dedicated to just your art tends to work quite well for spreading your stuff around. Sometimes it's not so much about personal preference but more about what works to get your name out there and to get a larger audience looking and commenting, which is what you want in the first place.But I need to say up front, I do not take Facebook or Twitter seriously (and Deviantart is great for casual chatting, even if not as a "base of operations"). Tumbler, on the other hand (spelled Tumblr - why the heck?), may be OK (unless I'm wrong about their permissiveness towards NSFW content). The "hugbox" of Deviantart I wouldn't mind. What I *do* mind, is the absolute silence I receive despite my best efforts to encourage viewer participation. Either I'm not trying hard enough, and/or this is a legitimate problem which is truncating my potential towards my quest for glory. At any rate, thank you for the link to the list of hosts, even if the article is a year old. I shall dive into those sites appropriately.
Tumblr is pretty good for art tutorials and posting up images (as long as Tumblr feels like posting them up), but watch out for the Social Justice Warriors. Tumblr's full of them.
