I think that tag inconsistencies like that are partially caused by the fact that moderators add tags they think are appropriate, whereas another moderator would add a slightly different tag that they think is good.
I've been tidying up some up inconsistencies by taking a number of tags that have the same meaning, check which is more frequently used, and change the tags on all the images that have the lesser used tag, to the most used tag.
Earlier today I did "flip_flops". That was the most used tag out of the others, that were: - flip_flop - flip-flop - flip-flops - flipflop - flipflops - flip-flips (lolwut)
