Ah, you're slow. VERY slow. The ODP has gone through one round of listing blogs (as a separate category); we've seen the weakness of that approach, and the ODP taxonomy has matured to the point of treating blogs like any other personal site -- "format" is a webmaster's choice, NOT a reason to accept or reject a site.
So blogs are treated like any other personal site (and, since most sites ARE personal, we've had a lot of experience with them.)
If personal sites are primarily about the person (that is, represent posts on a wide variety of topics whose only relationship is that they are all interests of one person), then they are listed in Society or Personal Pages categories, the most specific possible. If the personal site is focussed on a particular topic, it's listed in the Topical category. Sometimes for very popular topics there's a "Personal Pages" or even "Blogs" subcategory. But the ORGANIZATION of the site (that is, whether it's a blog or some other structure) is the LAST thing we look at when categorizing the site.
