After discussing it among ourselves, we think this is a really cute and fun idea! Thank you for bringing it to us. We'll put up a separate log for the Facebooking to keep the main logs uncluttered and make sure to explain how everything works at the top of the log. We chose a log because, as you said, it's neutral ground and will allow everyone to post without exploding your inbox.

Again thank you for bringing this idea to us and we hope you enjoy the fruits of your brainstorming labors!
