I'm proud that I've advanced as a writer to the point that, when a story of mine is rejected, the response tends to be personalized and encouraging as opposed to the form rejection standard.

If you haven't been checking out Tor.com, you really should. The site puts out some of the best speculative short fiction on the web, and they do it for free while still paying professional rates.
