Why would a DMOZ cat have zero PR?

Is lack of editing an issue?

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?

I'm no DMOZ expert, but my best guess is that it's just unpopular. However, that could be completely wrong. Maybe the PR is just temporarily showing as 0 due to datacenter updates or something.

TBPR is broken.

Unfortunately I don't think it's just that. When I do a Google search for very specific terms on the page within site:dmoz.org, it doesn't show up in the SERPs, although one of its sub-categories does.

Apart from internal DMOZ links there aren't now nor have there ever been links on this page, but there are other DMOZ pages like this that are indexed.

Since there are no outbound links, it can't have a bad neighborhood problem ... unless maybe one of the cats it links to has sketchy links?

Can you be a bad neighborhood based not on your own links, but the links of a page you link to?
