We're having a WorldChanging retreat this week, to sort out some of the issues we're facing as a new non-profit organization.

As a result, most of us will have little time to post. Rather than leave the page dark (or announce that we were going to have a week of "light posting") we thought this would be a good opportunity to re-acquaint folks with some of the pieces we've posted in the past that most clearly explored key worldchanging concepts, but which readers, especially newer ones, may have missed.

So, this week, we're running a WorldChanging Retrospective. We hope you'll find it interesting, and we'll be back, loaded for bear, on Monday.
