Unfortunately, the system eventually breaks down because a mutual admiration society develops and you see the same names again and again on each other's books. It seems to take too long for new blood to show up on the jackets.
How long do you expect it to take? I don't recall seeing Cory's name attatched to any of the blurbs for
Distraction or
Zeitgeist, for instance; and I'm sure that in five years we'll be seeing someone we haven't heard of yet on the cover of Cory's latest. Seems to me the turnover in names is roughly proportional to the turnover in authors, which seems reasonable enough.
