I noticed that a particular category that I care about has zero page rank. Any idea why this would be the case, or how this might possibly change?

Here's what I've ruled out so far:
(1) It's not new. Archive.org says it's been around since 2001
(2) It's not too far down. Its parent category has PR5, and so does its one sibling

I don't know if it's changed over time. Never tracked it before.

My best guess is that it hasn't been editing in a long time. Looking at Archive.org it hasn't changed substantively since at least 2005.

Is that feasible? Would an editing blitz help? Any other ideas?
