Could we have an 'I don't want to read this person's comments' button?
It would work like this. Each of us could specify 'names' we didn't want replies from, or comments from, and the result would be far fewer spats. People who respected each other could have civilised chats, people who couldn't stand each other wouldn't need to read provocative or silly comments.
What do you reckon? I'd bet there'd be quite a few who'd put my name on their exclusion list! And I have about a dozen I'd happily not hear from again. But the rest? I like and respect most on here.
