Note: To minimize confusion, we're now providing entry deadlines. They'll usually be Thursdays at noon Eastern time. You can still post links after that, which might still get included, but to ensure they get entered that's the time you should target. To enter, please use the blog comments to provide a link to your entry, plus any background information you'd like to share with us and other listeners.
