Should posts be tagged with wallpaper if they fit those dimensions, even if they weren't intended to be used as wallpapers? The wiki is not good at clearing that up. If so, then the tag seems pretty redundant since we can search by width and height.
I'm also seeing a lot of posts which fit the dimension criteria but do not have wallpaper tags. Not to mention a lot of resolutions which match mobile device wallpaper sizes also exist but are not on the list provided.
