Charlie Stross has another insightful post which he starts with a few semi-random links, and his readers then link them together into a discussion on housing, energy, homelessness and potential messed-up futures. Really interesting stuff.
And the commenters are both insightful, and courteous as all else. I can’t get five comments on some sites without being disgusted, but this is just a model community. Wish all site comments were like this 🙂
