Interesting framing. In this context, I think that the strongest argument for keeping a blog (or some other kind of public learning journal) is that it helps you bypass the IOED when you want to. If you have to explain in your own words what you just learned, with a target audience of “you just before you learned it”, that forces you to confront bits that you skimmed rather than understood, and to explicitly understand the boundaries of your new knowledge.
(I guess that a private journal might work, but making it public is a good way to keep yourself honest. “If someone else found this and I was being lazy, would it be embarrassing?”)

Paul Graham makes a similar argument here: Putting Ideas Into Words.
