There's plenty of challenge site out there. There are photography challenges, art challenges, fiction challenges, userpic challenges, you name it. I've realised recently though, that what I'd really like is a thought challenge. Once a week, or maybe once every two weeks, it would give me a write-up and link some resources on some philosophical idea, or perhaps a political, social or moral issue. Just something to think about. To expand my perceptions. So, lazyweb, is there anything out there?
