I mentioned that Google AdSense ads started to display in Google Buzz when you add your blog to automatically buzz. Today I have come a cross couple of tips in Gmail Blog about Buzz.
1) Settings to control what gets sent to your inbox
From the Buzz tab of Gmail Settings, you’ll be able to choose whether the following buzz items get sent to your inbox:
Comments on your posts
Comments on posts after you comment on them
Comments on posts after you are @replied on them
2) Explanations for why posts get sent to your inbox and an easy-to-find “Mute” link
You'll see a new message at the top of each post in your inbox that explains why it’s there: someone commented on your post, you were @replied, etc. We’ve also added an easy-to-find “mute” link that will stop subsequent comments from bringing the conversation back to your inbox
