Anil Dash asks how can blogs evolve? Blogs are too Loosely Coupled. They need to be better connected via HyperLinks but HyperLinks (as originally envisioned) are broken. Trackbacks were meant to fix this. Why aren't we using Trackbacks?
Too difficult to understand/implement.
Requires user education.
Dave Winer's oblique contribution to the discussion is also the most important and something anyone tasked with evolving the state of blogging should take to heart. Our contributions to a discussion, however oblique should be acknowledged. How do we get from here to a more connected blogging ecosystem? I wish I knew. What I do know is that the first three words on Anil's discussion page "Participant Sign In" are part of the breakage.
