Ain't it funny how a show like Marimite, which isn't even licensed has over 1,400 posts, while FMA, which is broadcast on a major cable network has only 69?

that is wierd!

As if American market situation had any bearing on the amount of fanart.

Keep in mind that the user base of danbooru is a very self selecting bunch. What appeals to the standard danbooru-er is only tangently related to what appeals to the normal TV watcher.

I wouldn't even consider danbooru to be a good guide to "fanart", too much sex.

So looking at google we have 4,990,000 for "full metal alchemist" and only 92,600 "Marimite".

And now try the same in Japanese, Sherlock.

Ok. So for "鋼の錬金術師" we have 1,610,000 and "マリア様がみてる" gets 997,000. While it better then the early number it clearly doesn't match danbooru's ratio. While there is a lot of noise, FMA has always been more popular http://www.google.com/trends?q=%E3%83%9E%E3%83%AA%E3%82%A2%E6%A7%98%E3%81%8C%E3%81%BF%E3%81%A6%E3%82%8B%2C+%E9%8B%BC%E3%81%AE%E9%8C%AC%E9%87%91%E8%A1%93%E5%B8%AB

Maybe it's because we're all pervs. FMA has a few girls with little sexual appeal, while Marimite is nothing but girls, all who are potential lesbians...except maybe Eriko.

Or maybe because FMA is meant to have some sort of meaning, which most anime fanboys fear like the light of day? :P
