Now, even Google starts to use Twitter, though not really the core of Google itself. We now have @Blogger and @googlereader. Maybe there are more out there, if yes, please let us know.

There is a blog post1 from Google that makes me thinking, which writes about Jaiku — bought by Google in 2007 — will be open-sourced. It’s interesting that Blogger and Google Reader chose Twitter not Jaiku. It’s not hard to understand, all because of amount of users.
