I read the article and here is the part I like......"The emerging answer is what Pickles calls “allowing users to control their own experience”, for example by using the mute button to screen out people they don’t like without that person knowing. Essentially it’s a way of allowing some tweeters to express divisive opinions without bothering others who won’t like it. One person’s right to free speech is matched by another’s right not to listen, as it might be at a party where you try to escape when trapped by the bore in the corner."...............Now that seems to me a much more favorable system than the one you are currently using. Give people a "mute" or "block button" that saves their preferences for who they don't want to see comments from. It can't get easier than that.
