But at a deeper level a blog is an authority router . Radio Userland take that to another level by fully decentralizing the power to both host and route the expression of authority. The power we grant others to author us . Inbound links is a good place to start. Syndications will be another one.
Referrals is already another.
That's what blogrolling is all about. Referring back isn't just reciprocity, it's metaconversation. It's an endorsement of value. Because we don't just refer back just to be nice or we would lose credibility. We point to what we think is worthwhile.
