OK, maybe I could have. The fact that I chose not to is a more honest assessment.
I just took a quick look at the viewer profile numbers for my blog again. Since I last looked on June 11th it's gone from 114 to 214 (100 in a little over a month). I have seen a comment or two and recieved an email or two - or three - since adding an email link to my viewer profile. I find it interesting to look at the numbers.
