Why I hate my username, and feel guilty anytime someone says 'love the username'
When we had to switch to 2.0 username Jeff wrote "the positive side is that if you have any old usernames like 'StartOrien' it'd be a great time to switch your username." Hitting a creativity blank, I went as juvenile as I could and just did what the teacher told me not to.
And now almost every time I sign in I consider deleting the account and making a new name.
