If you're an active user of Google Reader's social networking features who tried out Buzz, please chime in. I wonder if it really happened as automatically as it sounds, from the post, or if she missed something. (I've tried out Buzz, but haven't used Google Reader in months.)
I've been an active user of Google Reader since it went live, and I also have a Google profile. When I enabled Buzz, the only users added to my Buzz network were those already in my GReader shared network. Then I added a few others to Buzz. No problems here; no sense of an invasion of privacy whatsoever.
The rub is that I have no idea what results look like for those who don't use GReader or GProfile.
