Could we reverse the trend by integrating concepts like the web of trust into our search results? Alice recommends niche but highly valuable content from sites A, B, C. Bob recommends site D and trusts Alice, so his search results heavily favor results from A, B, C, and D. Jane recommends site E and trusts Bob, so her results heavily favor A, B, C, D, and E. And so on, this would have the power to bring those valuable, niche, but low ranking websites into the forefront. Some of the new search engines like Kagi have a partial implementation of this idea where users can uprank or downrank certain websites, but I think the true power of these rankings would come from a crowdsourced list that doesn't rely on very slow word of mouth distribution.
