OK, so honestly? When I decide to "blog the whole thing" for some of these collections, it may be hard to see the relevance to the Project, as such. And the real answer is that I like symmetry and follow-through. So if I've decided to "blog the whole collection" I prefer not to change my mind in the middle, even if -- in retrospect -- I probably should have just stuck to the two papers of obvious relevance. Another part of this is that it's hard to do anything between a one-sentence topic statement and a more detailed content summary.
