I also think the social aspect of it is pretty cool. I have spoken with a few folks that I found through other peoples’ followers, and people have found my profile through either their followers or authors they themselves follow. There are a ton of people in the community, and more join every day. I think it not only cuts down on degrees of separation, but also allows customers to find like-minded authors through those they already know. Much like any social network, it can expand your personal network exponentially over time. I hope this is a feature that continues to evolve, with new functionality added periodically. I would love to be able to cull an in-network notification list from it eventually, if not a full blown mailing list.
