Just read this from Inside Adsense. Non English bloggers will gear up with more content and in turn for more money. Indian bloggers writing in any of the Indian languages still have to wait.
"We're excited to tell you that AdSense for content is now supported in Croatian, Czech, Slovak, and Traditional Chinese. If you manage a site in one of these four languages, you can now complement your existing AdSense for search boxes (and revenue) with contextually-targeted AdSense ads!
To get started with generating your AdSense for content code, just visit the AdSense Setup tab in your account. Please keep in mind that after you add the ad code to a new page, it can take up to 48 hours for our crawler to access your site. Once your site has been crawled, our system will automatically detect the primary language of your pages and serve targeted ads in the correct language.
Welcome (or Dobrodošlica / Vítame / 歡迎) to our new AdSense for content publishers!
