Should I change the tags to English?

Like the question says, really. I originally had the tags only in Japanese, and then I added the English translations later so that it'd be useful for most of my blog's readers, who don't speak Japanese (or don't speak it well). But are they still useful? It makes it harder for other people to find the tags, they aren't in alphabetical order or even kana-based order--く comes before アfor some reason, for example--and a lot of the time when I'm writing, I'm in a hurry to find the tags so I just skip past the Japanese and read the English straightaway. Thus, a poll:
