Very true. I would gladly pay for a feed of financial news, but instead of "clicks" it optimizes on market movement. News articles from sources that, in the past, have predicted market activity.
I.e. "this blog mentioned NYSE:TEVA, and the next day the stock moved materially, therefore site_ranking++". (You'd probably have some TF/IDF saliency metric too, so that a site that mentions all stocks is penalized.)
