I dabble in writing; I've become increasingly proficient in keeping my condescending nature in check. Haven't written much though. Working on that.
A lot of my experience comes from reading, from books on writing, and from blogs on writing. I've also done a lot of critiquing at Critters.org, and reviewing at The Fix Online. Science-fiction and fantasy are my natural stomping grounds, but everything else is good too.
I'm also the proprietor of Short Story Squee & Snark, a weekly short-story discussion club. Every week we pick something new (and freely available), and discuss. If you've enjoyed spending time with me here on Writers.SE, I'd love to talk fiction with you over there as well :)
