Any truth to this....

I was told that to protect a tweeter from blowing, you can add an inline resistor that will absorb the current instead of blowing the tweeter.

Totally false.

A light bulb, a fuse, or the combination of a thermistor and a light bulb will all help protect the tweeter's coil from suffering a thermal failure.

Maybe you were possibly thinking of a capacitor as well? A capacitor in series with your tweet will act as a first order high-pass filter, so you'll be blocking the lower frequencies out which would have otherwise harmed your tweeter.
