Guess I missed that discussion. Shucks! I would've voted Nay.

I agree I don't think national wonders was the way to go. It is far to difficult to know how many of each building you have built in your empire so you go on building them after you have built the maximum number wasting time. Perhaps something like steel mill/Iron Works where you have one NW and then one building per x required buildings. This would scale and still let small civs produce some of the goods.
Brewery is a bad example since no one will buy the alcohol produced but you could have a national brewery and then one brewery per 5 or 10 graineries.
