As you've probably seen by now, we like to change things in Team Fortress 2. A lot. And while we're perfect most of the time, we occasionally get something wrong. One reason for this is we just don't get enough data from internal play testing, and another is that we spend too much time watching Tom Bui serenades on Youtube (Hint: Search for "Tom Bui" on Youtube) (Another Hint: <a href="http://www.youtube.com/watch?v=LmWv6gyRjCs">Click here</a>). So to help us change TF2 even more frequently, we're pleased to announce the Team Fortress 2 (public) Beta.
