So part 3 of the pledge is the one most often neglected: encouraging others to take the pledge. But this is arguably one of the most important parts bc otherwise how will it spread and change social norms?? So here is what we've had success with in Philly:
After the DxE forum we brought back a pile of extra forks to give to people who would take the pledge. Having a fork to hand someone on the spot seems to really encourage people to make a snap decision! I'm going to buy a ton and just start carrying them around now to help spread the pledge! We've got 5 new pledgers in less than a month the just by having extra cool for bracelets to give them!
