It's been 7 months since the 2011 Stack Overflow election, and it's been a fun ride, hasn't it? A few of us were just reviewing the entries, when we noticed that Tim Post, one of the elected moderators, is not present in the primaries phase.
Clearly, he was in the primaries since he got elected. But all 30 slots in the primaries are filled, and he's not there. Further digging shows that Tim's current reputation is insufficient to put him in the primaries when compared against the original pool of 56 nominees and their current reputation after 7 months. That is, the primaries phase of a completed election appears to filter based on the current reputation of nominees rather than who actually made it to the primaries.
Not many sites get affected by this, but it remains something to be investigated.
