Other folks have asked in the past why I picked my "handle." It is equal parts elementary school nickname, favorite Winnie the Pooh character, and general geographic locater (zip code). I came up with the handle when I first started commenting on a friend's blog. Much of the material there is related to local politics and other local issues. To the extent that I found some of the material resonating with my own local experience, I felt it necessary to indicate in some way that I was not a local, and that I didn't have a dog in the fight.
Because I distrust the relative anonymity of the web I have elected to keep a consistent persona in the blogosphere. The other thing that consistency in my handle does is make it easy for those who want to know what I really think to find my previous thoughts.
