As a self-published writer with thousands of downloads (at least of free eBooks), I'm somewhat disappointed that I'm still not a member of the Science Fiction & Fantasy Writers of America. Perhaps I never will be. The SFWA has no place for self-published authors.
I made the decision to self-published because I believed my projects were either too short, or not in a saleable format, i.e. short story rather than novel format. Every decision has its price. There's more than one way to be a writer -- some pay well but aren't glamourous. Becoming a popular fiction author is glamorous, but not simple, and very unlikely to pay well. Nonetheless, if one is sufficiently self-deluded one can pursue a glamorous career as an author of popular fiction. Only, don't quit your day job.
