Excellent industry update including circa 2014…

Over-specced (shows that have passed their prime, try to avoid doing them)
Mainstream (shows that have matured enough that they have become on-the-nose speccers–and a lot of people are speccing them)
Wild Cards (soon, everyone will spec those, maybe you can get a head start)
Outsiders (specs that will get you out from the pack)
Gamblers (risky shows that could pay off, or bomb)
