Indeed, you've hit on very valid point. One I think is usually the basis for any calls for categorization or rating. The issue of an increasing volume of users worried about missing good stuff. IMHO, most folks don't really want categorization.
Categorization is but one way to accomplish it.
But that discovery process seems unreasonably chaotic and certainly inefficient. This seems similarly problematic for distributed searching. In that you either cast too small a net and get no valid results or you crucify the network by casting too wide a search. All rights reserved.
