Wikia, Jimbo Wales' company, launched a search engine a while back. No-one really noticed, because it was dreadful (especially the ranking; it's pretty nonsensical), but it got a bit of publicity today, for reasons I'm not clear on.
Anyway, look what happens to the header if you search for 'cat':
It's not a bad cat, I suppose, but felines of far higher grade can be found with little effort on Google Images.
I'm not sure why anyone thought that endless tiled pictures of cats (or whatever; things turn up for quite a few searches) was a particularly sensible idea. It looks pretty dreadful, generally.
