I like that I can post content through email and text messages. That said, do we really need a single app that manages multiple 'circles'? When I look at my phone, my apps are my 'circles'. For close friends and family, I have text/email/Path. For my significant other, I have Pair. For college/social friends, I have Foursquare/Instagram. For mass distribution, I have Facebook/Twitter. Etc. With more and more apps offering Twitter/Facebook login, I can quickly pick and choose who I want to share an app with and form a 'circle' around that app.
