WordCamp Buffalo Slides: Selfish Accessibility

The Buffalo WordCamp shirt was again printed by You and Who (whose logo is visible where the tag would be), which means that 1,600 meals were donated (one for each shirt) to those in need. I think every WordCamp should do this. (related tweet) Buffalo WordCamp has just wrapped up…
