Wikia uses  gradients and   gradients - together those encompass a large portion of Wikia users, as Opera has a very low user share, and IE is used less frequently on wikis than on the rest of the internet. Per the murder of kittens, it's worth noting that loading a page with IE also causes kittens to die - and therefore has a much larger impact - whereas gradients are very likely to become standard at some point. So contrary what alistapart.com would like to tell you, TK, it is indeed nitpicking.
