Rating A Coaster

What exactly do the Buzz Level, Intensity, and Ride Again mean? It was a little vague to me, so if someone could help, I'd appreciate it.

Nitro: The Most Explosive Coaster on the Planet explodes at Six Flags Great Adventure in 2001.

In my mind this is what these phrases mean:

Buzz Level: How much this coaster should be talked about on CoasterBuzz

Intensity: The intensity of the ride; g-forces (positive & negative)

Ride Again: Is this ride worth the wait?

Yet another coaster-craving yuppie

My thoughts are the same, except Buzz Level. I think of that as how much fun it is.

Example:

Shockwave SFGAm, low-meduim buzz level, becuase it's too rough to be fun. Because it provides high G forces through the loops, it would still achieve high intensity.

B:TR has a high buzz rating and high intensity rating because it's very smooth, disorienting, high Gs, and plain fun.

Hey, SFGAm management, can I buy a couple cages of Sky Whirl?
