But these lists also already fulfill the need. When there's a category of something people are interested in someone will eventually make an "awesome list of ...". The good lists become popular and become included in various "awesome list of lists" improving their discoverability, while the bad lists fade into obscurity. And since there is no central authority and plenty of alternatives each list can be opinionated instead of including everything under the sun.

These lists follow the same "survival of the fittest" that underlies capitalism and evolution, and while coordinated efforts have many advantages they also have all the disadvantages of monoliths. I think a Yahoo-like site would have a hard time producing a better result.
