I'm sorry, I didn't see this discussion as well as the one before it until just today.
As others have mentioned, these evaluations were experimental on graduated sites. The philosophy behind them is potentially sound - just because a site leaves beta doesn't mean it's keeping up the standards and activity that makes for a successful site.
However, I have reviewed a bunch of the results and responses from this round of evaluations and in practice it turned out that graduated sites are doing as well as we would like them to and as I'm sure they would like to as well.
So we have disabled this review queue on non-beta sites. Thank you everyone who has participated in this round. You've helped us make and validate this decision. :)
