For awhile I was working on badges to give to "Official" accounts on StockTwits. These badges were given to professional users who were either Public Companies, worked in Media, or certain Professional traders.
Although the end product may seem as it is a simple icon. A lot of iteration and discussion/collaboration from the StockTwits team went into this. Along with creating use-cases as to where this badge would go (when you do a search for a user who is official, mobile search, recently viewed official users, etc.) I just wanted to showcase just a very few of those iterations.
You can roam around StockTwits.com and find some official users (Howard Lindzon, Herb Greenberg, etc.) to see the badges live or on your mobile app.
