A WOT or a whitelist is basically an invite-only forum. kmf's unique take on it is that everyone builds their own invite-only forum. As you point out, one issue is how do you find new people and content? I think a whitelist is too restrictive. I'm actually fine with 95% of people who post on this forum, for example. I'd just like an ignore function that works. When you add someone to the ignore list, it would hide the following: 1. Any thread started by that person 2. Any post by that person in other people's threads 3. Any post that quotes that person 4. PMs from that person The Philosophy, Economics and Justice subforum would be pretty empty for me in that case, but at least I would enjoy the content that I did see.
