Well, it was a close competition but we have a winner in the 140–character book review contest:

Workers are promoted to their level of incompetence. Explains School Administration [The Peter Principle]

Congratulations to Ted Sakshaug, winner of everlasting fame and a CASTLE mug. Ted, I’m not sure I like you making fun of all of those administrators I work with but the people have spoken!

Many thanks to everyone who submitted an entry and/or voted in the contest!
