You better explain how one is related to the other otherwise I will accuse you of trying to change the topic!
Perhaps I might, assuming this is what Chronos meant.
The Pluto-Charon system is approximately fully-synchronised. I.e., both bodies are tidally locked to each other. The remaining bodies in the system are not terribly massive, so their tidal influences ought to be minor - as evidenced by the tidal lock of the main bodies.
And yet, the surface of Pluto shows relatively limited cratering despite a collision-heavy environment (lots of junk floating around out there).
It's as if some source of heat was periodically melting the ices comprising the surface, smoothing it out.
Whether that has anything to do with tidal dissipation, and is not caused by e.g. the heat of collisions themselves, or anything else whatsoever, is unknown. But it's a nice topic for research, and who knows what we might learn once data from the New Horizons probe starts flowing in.

Or you could say Enceladus is one of the minute reasons Saturn is slowing its rotation. We must be careful with our semantics here, we do not know what the instigator is of the forces at hand!
I wouldn't put it that way, unless by the many 'minute reasons' you mean the many satellites (and rings) of the planet - after all, each of those migrating outwards 'steals' angular momentum from Saturn's rotation.
It's pretty well-understood that angular momenta in orbiting systems are being exchanged due to tidal interactions (i.e., gravity and friction).
