Edit: Also, you can show or hide the tab. So if you don't use Buzz and you don't want that tab shown on your profile, just hide it. However, this way Google can let their users that still use Buzz display it on their profile.
it depends on what you mean by "experience." I think buzz is easily superior to twitter, but I use twitter because the community I engage with is there.
does the existence of picasa's online albums somehow harm google because only some people use them?
Buzz is actually way more useful to me than facebook and twitter. The functionality is the same, obviously, but the fact that I can switch tabs while in gmail to check posts is pretty useful. Sadly I only know 2 people that use it, and mostly, it's automatic posts from twitter.
