> You use on the other hand to contrast two viewpoints. There are other idioms for enumerating more than two. I sometimes find myself using "on the other hand" to contrast three or more view points, and end up saying "on the other hand" twice. Occasionally, I'll use "on one hand...on the other hand...on another hand/on a third hand".
