Blocking--2reasons 

1. Over 1100 folks have responded to me and if I could get the size down of these threads and not have to spend a lot of time searching for the comment it would be far easier..

2. When Disqus introduced the blocking mechanism it was such a delight to communicate with folks I wanted to, only, and not have to skim all sorts of comments that were of little or no interest to me..... You are are making a number of assumptions about my desire for blocking that sound an awful lot like projections.....
