"Apostrophe Protection Society" ?! '
I can't believe no-one commented on this society, never mind all the apostrophe crap. I thought it was a joke but no. I nearly spent some further googling time on the "Comma Appreciation Society" or the "Which is the Best Bracket Conference".
But it's just one more example of stupidness. You do realise that like nearly every TV advert nowadays, they are going to put disclaimers on road signs too. "If you don't get there it's not our bloody fault" (obviously, some lawyers need to adjust the wording)
And perhaps add some apostrophes....
