OK seriously, the method for selecting people and assigning them to circles SUCKS. Tried 5 times to sort out 700 people and figure out who I have in a circle and who I don't have in a circle. Every time, once I had multiple people selected, I've ended up losing the selection.
I feel a Google+ rant coming on. This is a poorly thought out interface. Can't wait for them to get the API going so some useful utilities and tools can be released.
