I think that playing in a group that is *worse* than oneself is really hard work. For one thing, I am aware that I might mislead the entire group, which is an awful responsibility. I shudder at the thought that someone down the line might explain, Well, this is how Ebbie does it. aiaiaiaiiaiia

For another, it's just not much fun.

Playing in a group that is *better* than I am, on the other hand, is a blast. Not only might I learn something but there is great satisfaction in just sitting it out and listening.
