Everyone reads English and therefore I only blog in English. But if I were to start a site targeted to a specific geographical segment, I'd write in that specific language. This is the only logical approach, as I see it. If, of course, you can write proper English.
Agreed! I myself m' not a native English speaker, but I've good command over the language. Though most of my writings are in English but I'm quite aware of the fact that the level of effort one needs to be proficient in a second language is comparatively higher than that one needs to be well versed in native language (I'm talking specifically about the writing).

Well, adsense is not the end, there're more ways to monetize your blog, i.e. selling links and posts etc.
