Blogs and Blogging

If you spend a few moments clicking on "next blog" on Google-blogger blogs (such as this one), you will be struck, as I was, by a couple of characteristics:

• Fewer than half seem to be North American. A large percentage are Brazilian. Many are Asian.
• By far most of them are obscure, narrowly directed to a tiny specialized audience, or just personal small talk, of no interest to anyone who doesn't know the blogger.
