Unfollowing isn't an option because I'd still like to get the occasional post from Person X - just not as frequently as I'd like to see posts from Person Y.

I'm not talking about "firehose people" - my point is, it would be great if I could see (posts from Y) > (posts from X) > (posts from Scoble), even if they're all in the same Circle. Currently, everyone inside a Circle is given the same weight.
