I'm trying to figure out what good forts are - I've built a few, and put some defensive units coupled with some attacking units (for attacking damaged units etc) in them - but the AI civs just pass right by my forts. 
They would be a lot more useful if they had a little of the civ 1 feature where you couldn't move "alongside" enemy units, so if you built a fort in a strategically decent position, the enemy would have to go THROUGH the fort, and not just stroll along next to it while waving their hands to my defenders on their way to my cities.
Or let them pass by the forts, but have a chance of taking damage while doing so, to simulate being attacked by the fort when they move next to it. *shrug*
Edit: And the defensive bonus you get from forts is laughable. You get better from any forest/jungle, and equal from any hill. You can't build them around mines/terrain improvements either.
