My reading blog: "You Are What You Read". This is where I make notes about some of the weird stuff I like to read (and get story ideas from).
The Online Writing Workshop. A password-protected critique-exchange workshop for F/SF/H stories and novel chapters. Giving and receiving is incredibly helpful.
The Rumormill at Speculations.com. Market news and advice.
Ralan's market listings. F/SF/H story and poetry market listings--includes professional, semi-pro, and "for the love" rates of pay.
Story Pilot. Searchable market listings. Very handy.
The Black Hole. Market response times.
Inspiration. The best mind-mapping software out there. Keep track of your research notes with links to the web or files on your hard drive. Push a button to go from graphic view to outline. Push another button to dump your outline into your word processor of choice. You can download a free demo from the web site.
Dramatica writing software. Not for everyone, but I have "Writer's Dreamkit" and love it. It has really helped me focus. This site also has free demos available.
Furl web-link organizer. Get a free account with furl and keep track of all those sites and articles you find on the web in the course of doing research for a story or novel.
And that's probably enough for now!
