You have to keep in mind that the original google search, by summarizing search results based on links between pages, essentially destroyed the web of interconnected links that existed at that time, so that the original pagerank algorithm doesn't even really work anymore. And the search results Google returns are worse than they were years ago. And you know, I use it, it is still super convenient, and the long term effects took some time to become apparent. Now it is again feeding on and regurgitating Wikipedia but again in a way that will end up destroying the thing it is summarizing. Aggregators are parasitic on the thing they derive information from.
