Hot spark plugs are better insulators which keeps more heat in the tip of the spark plug, and therefore in the combustion chamber. Usually, copper core spark plugs are used by older vehicles, and the number of newer vehicles that can use them is getting smaller by the day. These tend to last longer than cold spark plugs, because temperatures are high enough to burn off carbon deposits. Basically side-gapping is shortening the ground electrode so it exposes more of the spark to the incoming air/fuel charge, similar to the idea of indexing plugs to have the ground electrode's base aimed away from the air/fuel charge so it doesn't block the spark.
