Editor's note

It’s not often that we’re able to get the staff of The Conversation together in person, but yesterday and today our Boston newsroom has been humming with colleagues from Atlanta, New York, Seattle and Washington, D.C. in town for two days of brainstorming and bonding. We’re excited to be talking about the future potential of our unique scholar-journalist collaboration. That also means that we’ve been away from our desks and our computers. So instead of your usual newsletter, here are some of our “greatest hits” among readers from the past four years. Enjoy – and we’ll be back to regular service tomorrow.
