I didn't sign up, but I'll give you feedback.

Your main competitor in my eyes is Facebook. The "circles" you promote seem similar to "friend lists," an underemphasized but existant feature on FB. I can publish content to only certain lists with a few clicks. It's kludgy but doable. I manage only one list on Facebook because that's all the granularity of privacy I need. Most people care less than I do, so I don't see a significant need.

Cool design, but the text on the infographic seems off (perhaps it should be actual text and not part of the image). Your about us page is not terribly long yet still wrought with syntax, grammar, and word usage mistakes.
