Another vote for nested and Venn-able circles. And thanks for this new functionality.
What I've had trouble with on the Circles page is the awkwardness of the two frames on the page when viewing it in FF. The bottom frame won't scroll to the bottom of the page (the Send Feedback widget might be blocking part of the scroll bar), so I can't see the titles of the bottom row of circles to know where I'm trying to drag someone.
I think it's going to become necessary to make some circles Send-only and some Read-only, and also some publicly visible and subscribeable -- I may really want to read someone's tech things, but not so much their political or religious rants. I like the non-reciprocal nature of circles -- I can follow someone without requiring them to confirm our relationship, or even know who I am -- but I think some circles might function better if that reciprocallity can be massaged at the circle-level.
Oh, and I guess it's becoming evident that I want circles to have circle-level tweakable attributes.
I'm happy to discuss any of this that's less than clear -- I can't always get the words to succinctly carry all the meaning I want in more technical concepts -- and I realize that they are much easier for me to think up than for you to create, so I don't expect them to be done next week (the week after would be fine, though). Thanks for all you're doing here, it's a cool place.
