Not sure about this
Glenn Greenwald via Atrios:
The blogosphere is a hard-core and pure meritocracy. It doesn't matter who you are or what your pedigree is. You either produce persuasive arguments and do so with credibility, or you don't. Whether someone has influence in the blogosphere has nothing to do with their institutionalized credentials and everything to do with the substance of what they produce.
I suppose there are elements of truth in there, but by and large, this strikes me as a much too rosy view of Blogland, especially its right half. I mean, come on: is Instapundit's influence really due to his "persuasive arguments"? I don't think so.
