This is a puzzle. Now that Facebook has subscribing, it makes a lot more sense to me. I feel like it's about to become meaningful.
And I think the people I share friendships with on Facebook just became more valuable to me, and me to them.
But now I really want to get my Blork feed to flow through there.
I'm scratching my head over their API. I'm sure it'll start making sense real soon now.
Update: They use OAuth 2.0.
