I'm lucky enough to work at the intersection between information communications technology and civil rights/civil liberties. I get to combine technical interests and social/political interests.
I've talked with many folks over the years who are interested in doing similar work. Some come from a technical background, and some from an activist background (and some from both). Are you one of them? Are you someone who works as an activist or in a technical field who wants to look into different ways of meging these interests?
Some great organizers maintain a job board for Digital Rights. Next month they'll host a Digital Rights Job Fair, which offers an opportunity to talk with good people at organizations that fight in different ways for a better world. You need to RSVP to attend.
