Given the populist sentiment about the way it launched Buzz, by merging it with Gmail, resulting in a million-and-one privacy kerfluffles, Google's now thinking about going beyond the tweaks it made the other day by cutting the cord between Buzz and Gmail entirely.

Update: Or maybe it's just getting a separate app. Hahaha. [Search Engine Land]
