Yes, quite often.
I mostly write story ideas, fanfics and original short stories. Only a few ever leave my HDD, and some of the ones I've decided to flesh out beyond a measly 10k-15k words or so get put online. I've got at least 15 seeds (as in, story beginnings) at 8-18 pages long, waiting to see if I decide to go anywhere with them.
I've dabbled with poetry enough to know that I shall never be even a part-time poet.
I made a promise to myself that this year at last I'd finish writing a full manusript and take it to a few publishers, see what they think. 150 pages of raw text done so far on that one...
