I've posted some drabbling on tumblr but my legitimate stuff I post on figment.com. There is an anti copy-paste code in place that keeps the thieves away.
I post the rare piece on dA because I know I can ninja it out of existence if need be, and that's really it. I tend to write poetry with publishing in mind, so I don't put it anywhere unless I can set fire to every trace of it having been on the internet.
I've debated getting some literature up on DA, but the submission software swears up and down that, even after I've made multiple versions of the same document, that I am not in the right format...
Nowhere. Mostly I write novels, which I am interested in having published eventually and which I don't think read well online (never mind getting committed readers). Posting online is generally not feasible for my goals, so I tend not to. Unless I decide to write something short for a contest or am not interested in publishing. Or haven't been able to publish for whatever reason.
(I used to post over at Cafepress every once in a while, but deviantArt's community has been the most rewarding for me feedback-wise and community-wise).
I like Hello Poetry.
