There are many good things to read online, or to download for reading offline, and Free SF has recently added a number of them, including works by Walter Jon Williams, James Patrick Kelly, and Felix Castor, to name a few. One of my favorite places to go are the online Ezines, like Flurb. Headed up by Rudy Ruker, Flurb concentrates on quality stories that for one reason or another would be very hard to get into a normal print magazine. Then there is Clarkesworld, currently with Herding Vegetable Sheep along with some other stories, at least one in audio format each month. Another good one is Raygun Revival, concentrating on golden-age space opera. Strange Horizons usually only has one story and one poem per edition, but it comes out once a week, so you still get a months worth of reading. There are many more, but that should get you started.
