Yahoo! & Google results in a single page

Ever wished to get both Yahoo! and Google search results in a single page?

Yahoogle! is a search-engine-mashup built to put the top search engines to the test. Google is the most popular search engine in the world but there has been recent fanfare saying that Yahoo! provides the safest and most relevant results. Now the links are anonymized so we can see which engine really does give the best results.

How does it work?
Using Google's and Yahoo!'s search APIs, the top five results from each query are intertwined. Keeping their relative order the same, they are mixed randomly in order to ensure an even distribution across the front-page. To make sure that clicks aren't biased, the results are anonymized by displaying them in exactly the same format. As a result of this, as stipulated by the TOU for each API, I must attribute the respective search engine for providing a result. This is why there is a confirmation click-through dialogue before opening the requested page.
