My librarian self is fretting: she wants to group all Astronave's like-minded posts together. Take today's addition to the "Star Trek and Art History" category, for instance--would not it be better if it sat next to the other posts on the same subject?
If so, when is the correct time to rupture the blog's chronological order?
Or does the tag/index suffice, and my inner librarian should let go of her old-skool Paper Brain?
