You can read some great science fiction and fantasy for free online. This is nice for aspiring writers, looking to see how good stories are constructed, and it’s nice for readers who simply enjoy a good story. These aren’t just b-rate venues, either, markets both elite and humble have online content.
–Clarkesworld– one of the best venues in science fiction.
–Daily science fiction– they have a great subscription list. Sign up and they’ll send you one story every business day, mostly flash fiction .
–Escape pod– a science fiction pod cast. They also have sister horror and fantasy podcasts (pseudopod and pod castle).
–The colored lens– they have new stories weekly. If you’re interested in submitting works, this is a great venue as they respond quickly and personally. And there’s no better way to see what a venue wants than what they’ve bought before.

Happy Monday! (This late, possibly oddly formatted post brought to you by my busted computer screen and my phone.) :)
