Its informal membership includes of some of the most interesting minds in the world.

That sounds impressive, till you start trying to work our what "some of" adds up to. Not too much.

Strictly speaking that could include just about everyone. Well, I suppose there'd have to be someone somewhere who wasn't included, but everyone else would fit into that.

Of course the same would apply in the case of the "some of the least interesting minds in the world".

And both expressions would apply to the Mudcat membership.

Of course I can't prove that, but I believe it.
