So would this be considered an email first project? I had an idea for website called "Global Voices" (domain will be glblvcs.com) Users from all over the world will enter their email and subscribe to a micro-newsletter that comes out every Friday night. By entering their email they're also automatically entered into a "lottery". Every week 3 lucky people are chosen and each get to ask all the users 1 question which will appear in that week's newsletter. The 3 questions in each newsletter will link to a message board where people from all over the world with diverse backgrounds and cultures can answer the questions if they want. I think email in this case would encourage participation. If you're not subscribed and getting the emails you don't get a chance to ask a question. By being subscribed you have a greater chance at returning to the message board and writing an answer. Thus fueling the community. Sound good?
