Its fantastic that Blogger has gone multilingual. An internationalized blogging platform that is localized in 9 languages will have tremendous impact (Socialtext is internationalized so far, btw). But this is Google, which the world increasingly trusts as its knowledge base, and is doing great things, but you have to wonder what can be done about language discrimination.
Its less a matter for Blogger, but with Google, small languages will not be supported when development is driven by market forces alone. Regulated development would of course be disaster. But if there is an area to call for open source in search this is it. Enabling localization, and perhaps even machine translation, according to social incentives could bring our world together in ways we cannot design.
Then again, if vertical information assembly (coding) isn't open on a global platform, we always have the horizontal.
