Something should be done with writing desk
. See, the character mostly known as Raven shows up in two forms in the show and merchandise, as an earth pony and as a unicorn, and serving both Princess Celestia and Mayor Mare. Some people thought that this meant that there were actually two (nearly) identical ponies and suggested that there be separate names for the unicorn and the earth pony: Raven (Inkwell) and Writing Desk. This sort of fell apart and died, though, because Hasbro itself can't make up its mind about whether Raven is a unicorn or an earth pony.
The upshot of this is that there are a few dozen images tagged "writing desk" that depict a character identical to the one tagged "character:raven" (also one image depicting an actual
writing desk), and some that are tagged with both
Writing Desk. This seems like it should be fixed somehow. I reckon there's three possibilities. First, just go through and tag all of the Writing Desk images with "character:raven," then remove the Writing Desk tag from them (leaving just the one image). Second, go through and add a "character:writing desk" tag to all of the images of Raven that "should" have it, then remove the old Writing Desk tag. Third, alias Writing Desk to character:writing desk or character:raven.
Personally, I favor the first option, since in practice the Writing Desk character/tag has basically failed (as I said, Hasbro itself doesn't seem to be able to make up its mind whether Raven is a unicorn or an earth pony, to say nothing of humanized or anthro versions where it's unclear which possibility is intended) and people looking for Raven images probably want to see "Writing Desk" images too. But I figured this is a big enough change that I shouldn't just do it unilaterally.
