Interesting. However, many people already filter the first page, let it be by points, or by the twitter accounts:

http://twitter.com/#!/newsyc20

http://twitter.com/#!/newsyc50

http://twitter.com/#!/newsyc100

http://twitter.com/#!/newsyc150

And from each filter, people auto-select things that interest them. Sometimes I only see a story when it is retweeted to me.

And this you can't prevent. It lies on the fact that different people have different definitions of what "quality" means.

Which is the core problem highlighted by linked blog post.
