It'd be great if Google+ allowed you to mark a Circle as public.

For example, if you find an amazing person in field/topic X - I like to see who that person follows to try and find more awesome people. Google+ provides Circles so that you can organise your online relationships, which I assume most people do but the Circles you create are private unless you directly share them (I think).

I'd like to be able to create a Circle & mark it as public so people can see that I've placed people A-D in list Y because they are awesome.
