Ezine publication can be a great way to get your name out there. And depending on where you are accepted, it might make you a little money. Some great sites for finding places have been listed. I use duotropes most often, but honestly, I started by finding a few, narrowing it down to the ones that seemed most like my writing (which is a rather specific sub-genre) and then kind of followed links from authors and zines to other places, building up my roster of places that accept me. Authors who write similar stuff have links on their sites to other places they appeared.
I haven't gotten the novel published yet, in spite of my stack of published shorts, but I have developed something of a following. I haven't gotten rich off it, but that's because most of my work has come out in little ezines that don't make any money, let alone pay it. I'm okay with that. I never do get into the "Big" markets... either I don't write good enough or they don't like my style. I like to comfort myself by thinking it's the latter.
Best of luck, Ugawa!
