Bronwen - I'm asking the same question.
It actually goes further back than you post.
For me, it started with Tech.Ed 2004 when we were in Canberra. I asked for some flair, or at the time, we called the Blog Buttons. Berno (who at the time was a student) got some made
Then in 2005, we introduced the official flair
which then got mashed up and generated 100s of entries and ended up on tshirts, including this one
Last year, we had official flair again
Which inspired some more user created flair
And of course, we also had the meegos
Which now brings us to 2007. What do we have? Well, there is no flair - that's for sure.
I started the whole TechEd LOLcat thing but still no flair.
What's going on? I'm going to wait a day or two and then I am going to start a campaign
