It is best to follow 100 feet or more. This gives you space to react to and avoid debris flying back at your car, and more than enough room to stop in the event of an emergency.
Added: While the "10 feet for every 10 MPH of speed rule" is a good guideline, the above answer is a good one for following a commercial truck or bus. If you get too close to the rear of the truck/bus you move in too close for the driver to see you in his sideview mirrors and you are too close to see anything around the truck.
You should be far enough behind that you can see their side-view mirrors. This gives assurance that they, in turn, are able to see you. That's a minimum. Ideally, you would want to remain 200 feet or more behind them, in order to minimize risk of damage to your windshield by rocks picked up from the road.
If you are behind a truck and you CAN NOT see his mirrors then you're in his blind spot and he can't see you.

When driving behind Semi's, Buses, or large Trucks that obstruct your vision the rule of thumb is to maintain enough distance behind as to be able to see over the truck. If you cannot see important road signs ahead of the truck, chances are you're following to closely.
A box truck is a truck with a box attached to the chassis behind the cab. Think "U-Haul", "Penske", etc. A bobtail truck is a truck-tractor, also known as a prime mover, which uses a fifth-wheel hitch to tow a semi-trailer. Think of an 18-wheeler without the trailer attached.
