While we are on the topic of too much work and not enough people to do it:
Tonight I felt particularly motivated and decided to make myself useful
deleting superseded images. Trusting the people who had posted those
images there I made my way through the first dozen or so of the list, when
I suddenly decided it might be a good idea, just to be on the safe side,
to perform a check-usage on those images. Turns out some of those images
weren't only used on one or two Wikipedias, but more than a dozen. So I
ended up undeleting most of the images, because I really got better things
to do than first check all those images if they're still in use somewhere,
and then making I don't know how many edits in as many Wikipedias changing
the links.
So I think if we ever won't to work off the backlog we have accumulated we
either "train" the normal users to fix the links when they add the images
there or we find some possibility to do it automatically using bots
running parallely on all WPs or something.
I don't know if that's possible to implement, but I for myself have better
things to do than do all of this by hand.
