I love this idea: Guerrilla forces adhering letters and removing apostrophes to conform to the basic standards of human communication. Grammar vigilantes, patrolling the night with cans of spray paint and stencils. Capitalization crusaders, if you will. Eh, that was a bit forced. Anyways, it reminds me of one of my favorite books (interview with the author here), one I came very close to buying for a friend's birthday. Ultimately, I decided against it because it's such a short read that it's better as a rental. If only there were some sort of shield law to protect this sort of vandalism or government endowment to correct the most grievous of errors.
