Looking around the lowest rated page, and looking at the total number of entries, i think we could stand with a scrubbing.
It sounds rather draconian, but i think we could cut everything below -2.
Honestly, most of the pages in the negatives will not recover. They tend to just keep going down, slowly but surely. We can keep them around in hopes that they recover…but honestly, how likely do we think that will be?
Is this too extreme? I'm wanting to start offloading some of the less impressive work we have on the wiki, and this seems like a good place to start…
