Mythbusters

Rachelle Gardner did a three day series on busting (or confirming) myths of the publishing world.  I linked to the third day but you may want to read them all.  There wasn't anything earth-shatteringly new but it was a good read and kept things in perspective.  I especially liked the breakdown of what you get out of a six figure advance.  Did you find anything new?  How about any myths you didn't see discussed?
