When I first started visiting and commenting on other people’s blogs many years ago, I needed a gravatar and a screen name. Although I settled rather quickly on the grumpy bluebird for my gravatar, I went through a couple of different screen names before settling on one that actually suited my profile picture — the bluebird of bitterness.
When in a moment of temporary insanity I decided to start my own blog, it only made sense that I would name it after my gravatar, and so the bluebird of bitterness blog was hatched.
One more thing: although I identify as a male bluebird online, in real life I identify as a female human. I was gender and species fluid before it was cool.
