My old standard submission destination was Weird Tales (http://www.dnapublications.com/wt/index.htm). Now I'm gunning for Fantasy & Science Fiction Magazine (http://www.sfsite.com/fsf/). That's a great idea regarding the Year's Best... anthologies. They would give a good indication about which magazines are actually being read and taken seriously these days.

I suppose I am technically published, too. I had a short story published in BARK! when I was 16 or 17. This magazine was one of those hip and sassy things targeted at high school students. It was apparently short lived, as I can't find any mention of it online. These days there is a Bark magazine for dog lovers. Not the same one.
