Wikipedia + Google
Implications - According to Wikiseek, the innovative search engine makes use of "Searchme's category refinement technology" in order to provide "suggested search refinements based on user tagging and categorization within Wikipedia." The result is that those results that are eventually received are "more relevant than conventional search engines." As a result, searches made through Wikiseek are ultimately far less likely to produce results that are cluttered with SEO-abusing sites and spam advertisements. Nifty!
