We're all super excited here at mediabistro.com because our newly launched Mastheads Database has reached heights of popularity not seen since the union between chocolate and peanut butter in 1928. A few days ago we passed 200 mastheads. More than half of those bad boys are from national magazines. The mastheads also feature recent job changes and email naming conventions. So, if you're one of those folks that loves Playboy strictly for the editorial content, you can now study their masthead and maybe even pitch one of your own "I can't believe this actually happened to me" articles. We know you're all hitting the site now like maniacs, but remember that only AvantGuild members get to look. If you are a member, click here to start the insanity. If you're not an AvantGuild member, why not sign up?
