Since only a couple of people have mentioned the Hanging Gardens, I want to bring it up again. There is really nothing to dislike about this wonder -- +1 health in all cities, +1 population in all cities, never expires, and Great Engineer points. and it's not too expensive (300 hammers, sped with stone). Population = power, always has in civ games. The only potential problem with the Gardens is if you have quite a few cities at their maximum happiness, but even then the free person is just waiting for more happy faces to come in through another resource or (more likely) a building.
I also wanted to second KAuss's point on the Spiral Minaret. Shrine + Spiral Minaret + Wall Street is a very nice combo.
And The Colossus is a great wonder for a financial civ with more than a few coastal cities.
Finally, I have heard from a reliable source (Sirian) that the AI gets no production bonus on wonders at the higher difficulty levels. I haven't tested this myself, but I see no reason to doubt what he said. Something to note in any future article.
To other posters: instead of just what wonders are good, which are a waste of time. Which can easily be avoided.
