So, many years ago, Analog Science Fiction & Fact was edited by the great Dr. Stanley Schmidt. A truly fine editor. (The current editor, Trevor Quachri, is also awesome).

Dr. Schmidt never switched to email and electronic submissions. The magazine switched only after he retired. Old men get set in their ways ;).

Somewhere in one of my desk drawers is a blistering type written rejection from Dr. Schmidt. In it he informs me of every scientific error I made in the story. I think there might have been a typo or two in there. It was a full page of "Here's exactly how you're wrong."

One day I plan on framing it.

Because I stared at it and went "OMG. He took the time to tell me about all my science errors. I must be able to write."

Editors don't write long personal rejections to people they don't think can write.

Edit requests are, indeed, a compliment, but a good rejection can be too.
