the slushkiller post from teresa nielsen hayden has made its rounds in the last couple of days, and i'm sure most folk saw it then, but there's more interesting things in the discussion below it as well. the things about agents caught my attention, specifically, but this might be because i am in the middle of trying to see if i can snag one. but it makes interesting reading, since you have charles stross and neil gaiman putting in their own little opinions and experiences.
anyhow, i thought i'd link it for people who had a look a few days ago, and haven't gone back. just scan for names you recognise.
