Eddie, I really like how you differentiate between a member and a citizen. Ryan Barrett’s definitions are also useful. The one thing that really helpful was your closing statement:
Someone who expresses a large commitment to the IndieWeb, I would expect that they post the majority of their text and photo based content on their website. That doesn’t mean they can’t also share that information on silo-based social media, or that they can’t occasionally put information that they see as ephemeral directly on Twitter or Facebook. They are welcome to do whatever they like, but if someone has a true commitment to IndieWeb principles which the citizenship language leads me to believe, I would assume the majority of their thoughts and photos are posted to their website either through POSSE or PESOS
I wonder if this opens the door to platforms and providers like WP.com and Edublogs.
