I came across this site a while ago, and forgot all about it until I got an email telling me that a question I'd asked had been answered. It's a really interesting site run by a couple of philosophical societies.
Basically you post a question about philosophy, then one or more philosophers post the answer. The archive of questions and answers is really fascinating, and only some of it is too esoteric for the lay person.
My question was - Is conscription morally right? If you want to know what the answer was, go to this page and do a search on 'violet'.
