Why doesn’t an associated account appear in my flair on Area51?
Whenever it shows your name with your reputation and badges, underneath that it shows little icons of all the sites you participate in. For example, on this page you can see Jeff's name on the right with 6 different icons representing the different StackExchange sites he is a member of.
How come I have accounts on StackOverflow, SuperUser, and Meta, but I only see icons for the first two sites (i.e. there is no Meta icon)?
(My guess is that there is a minimum reputation you need in a site for it to appear there. If that is the case, what is the minimum?)
