I have found some good sites for writers recently, and I thought I would share some of them:

Duotrope Digest is a free site with market listings (many small press markets) - they've got stats such as how long the average wait for a response is, the ratio of acceptances to rejections, etc. The listings are easily searchable by pay scale, genre, whatever you want. Also if you become a member of the site, you can keep track of your submissions with a submission tracker, which I've found useful.

The Free Dictionary. I use online dictionaries quite often to look up words, both because I am lazy (you have to get up, and drag the dictionary off the shelf, as opposed to a few clicks), and because many of the words I want to look up are not in the dictionaries that I own. I just recently discovered this site, which also has word games. The entries have an icon to click and hear the word pronounced. (I know it's not always a good idea in writing to use a $50 word you know just because you know it when there is a $5 word that will do the job, but I'm a word geek, and I enjoy learning new words, useless or not.)

Free Rice. Another vocab-building site. This is a game, multiple choice answers to choose from to define a given word, and it automatically adjusts to your vocabulary level, getting harder the more you answer correctly. Plus, for each correct answer you give, rice is donated to programs for the elimination of world hunger.
