Absolutely, I think this is exactly the BIG idea that the VCs saw that others didn't really get. I would add that I don't even think it's about "friends" in your elastic social network, it is that the social network exists based on the context (where you are, who you're with, what you're doing) regardless of whether the other person knows/friends you or not. There is a shared thread that is tied together by a shared experience and Color was trying to capture that.
