At the top of this page, there's a link that says "Next Blog". It leads to another random blog on Blogger.com. I sometimes click it. More often than not, the target is not in English. The absolute leader is Portuguese. Next come Malay or Indonesian (they're pretty much the same language that no-one actually speaks but a lof people write). Spanish and Japanese are quite common too. And that sorta makes sense, 'cuz a lot of people speak those languages (although the absence of French and German is rather obscure).
But all too often i come upon Icelandic, a language spoken by less than half a million people.
