A good point borrowed from Andrew Sullivan.  Does blogging create too many critics and not enough readers?

It’s tricky, because it becomes a question of the process of democritazation–on one hand, it’s wonderful to have so many various “leaders,” yet it just becomes much more difficult to find where the good writing is.

And then a larger question: is there really ever any good criticism?  Or is it all arbitrary, contingent only on social position and convicing enough people you’re smart?  This is the modern art problem writ large.
