Another link to TNH's excellent blog Making Light, this time covering a subject that's been a bit of a hot topic on Israeli SF forums as of late – stories and books that have been rejected for publication, and the (evil, nefarious, and dastardly) reasons for said rejections.
Dear rejected and dejected authors, please read this. Read this through. The writer is an editor at Tor, and someone who knows more about publishing than you do. Heck, she knows a lot more about publishing than I do, and I've been a pro editor for over six years.
Link via Neil Gaiman, btw.
