I'd also like to be able to mute specific users. I love the follow feature to get updates and read comments on blogs.
However it also means I get lots of emails "Nice blog thank you" over and over again from the same user. By the same user I don't mean one specific user I mean users that go to multiple blogs and add the comment like "Nice blog thank you".
The emails seem to have an ebb and flow of their occurences
