I thought the global reputation graph should include those sites on which I have at least 200 rep but I haven't found an authoritative source for that, and that's not what I'm experiencing now.
At of the end of July 22nd my reputation on Apple.SO and Programmers.SO was over 200, higher than my score on Super User. It's been over a week and the graph still doesn't include them, even though the scores listed for the sites it does include have been kept up-to-date.
I thought this was a misunderstanding or bug just with the reputation graph. I just realized that the other sites are also missing from my global flair image, so I guess the bug is a bit more general than that.
Has anyone else passed 200 reputation and had the site show up for them within the last week? If so, the issue might be specific to my account, and I might poke someone to have them take a look at it.
