Ask HN: How up to date is your documentation?

I'm attempting to solve the problem of stale documentation. Docs are incredibly important throughout tech but unfortunately they're commonly left outdated.

While this is probably a cultural/time management issue, I'd like to get some insight into the tools other developers use and their opinion on the matter.

I created a Google form and I'd appreciate any submissions or even discussion below.
