Given the many ways in which people use blogs, especially in the post-Twitmachine world, in which the internet is largely used by people to send smiley-faces, unclothed photographs, and intemperate and incoherent political exclamations to like-minded folks, that this is an old-school, 1990s stream-of-thought type operation, not really an attempt to communicate anything to anyone. I'm literally sometimes listening to Pearl Jam or Phish (TAB, technically) as I write these things.
One writes because one thinks, and a convenient means of recording these thoughts is at hand. And, the world being the world, this is undoubtedly being used by devious others in evil ways. But, as the fellow says, quod scripsit, scripsit. And this is also a limiting principle.
