FYI, one site that is becoming increasingly important to me is Free Speculative Fiction Online (
http://www.freesfonline.de/Authors1.html). It seems to be the most complete source for finding free online SFF short stories (mostly) and free books that's out there.
I use it for 2 reasons
1. Just read a new author (for me), and want to get all the free stories that are available for that author.
2. Seeing what "new" online stories are available for an author (currently looking for William Tenn). The New Additions tab does have an RSS feed, which is handy in seeing if there are any of the "new" stories are interesting, although each of the articles take you to the same place (top of New Additions tab).
