Two things first you can try setting up something through public libraries. library science majors are pretty plugged in and know about tags and all that. Secondly, while everyone tries for the "youth" movement (and trust me it's fairly useless most people I know don't blog unless you count livejournal) reaching the elderly is a good cause. After all they have plenty of time on their hands, are willing to reach out to yahoo for games, and are willing to embrace things that allow them to connect. Last, design is so essential these days really writing a text book, or getting someone too, would be a good idea. Teach kids early about the advantages and concepts behind information sharing. make design part of a schools curriculum. and of course, sometype of firefox like taking an add out in the ny times (although frankly I think the problem with political campaigs is they too often focus only the ny times and not say the times-picyaune in new orleans etc.) I had an idea for creating a wiki like wikpedia only for textbooks. open source history books etc. would make it easier for people to learn basic things and to study the currents in thought as they happen. modify tht physics text book as it happens etc.
