I am in love with Slush Pile Hell. The blog is subtitled: A grumpy literary agent wades through query fails.
The blog itself is full of the awesomely bad from query letters and the awesomely awesome one line responses.
Particularly, see July 26 regarding Oprah and authors. And there's more recent brilliance if you make it through the contest entries to previous days posts. Actually, they're all brilliant, so keep reading until reality intrudes and threatens to chop off your mousing hand.
