I agree with you, especially in light of your "generally" caveat, but taking the lesson from the Holmes quote above... there are contexts in which the easily accessible approach of a blog post is far more valuable than a journal article on the same topic, along with the ability to provide prompt updates when the situation changes.

Context, my dear Watson.
