Actually he wouldn't since he isn't in the top 30.
I'd expect the list to change fairly dramatically once people need to make their own lists instead of relying on default trust though.
I like it. Most people aren't going to stop using default until they have to.
The only problem I see with this system is the top xx people will continue to gain more trust and will pull ahead of the rest of the users. You're basically replacing the DefaultTrust with those people.
Only if they stay on their lists, and if they do stay on it, then they deserve it don't they?
