What they got right: Whiny fanboys. Comic "investors". Publishers and Editors-in-Chief suffering from Eventitis. No one is spared, and it's all in good fun.
What they got wrong: Now if only the aforementioned would take those lessons with them, maybe blogs, forums, and the comics themselves would be more enjoyable to read. (Not counting mine. Mine is totally enjoyable. Bias? What bias?)
Recommendation: Pick up these comics (unless the joke continues into a Trade, which it should, with an in-character Krusty exposing the virtues of trade waiting as only Krusty can) and maybe get some for the obsessive fanboy in YOUR life.
