A lot of people don't share because it's another step, but if they could install an app like the Washington Post Reader (a great app--even Mark has it installed), they are happy with sharing articles they've read with their friends I can't see the logic in this. I don't know if I want to share something until I've read at least some of it. I don't want it shared as soon as I open it in my browser. There should be another step...
