Really cool reading this back story, in 2010 I launched a web search engine that displayed search results as favicons (no text, image only). The goal was to appeal to kids (using images and not text) and mobile devices (I generally find only 3 search results fit on a mobile screen using standard search engines, but the favicon engine allowed a user to see 30 search results on the screen at once)...the traction did not last and it was shut down. Nevertheless, great learning experience and my fondness of favicons and their importance only grew.<p>Edit: The part about Yahoo also made me recall a prior version on Yahoo's mobile search which displayed favicons prominently to the left of the search result text (first thing your eyes saw was the favicon), and at the time I felt Yahoo had the most aesthetically pleasing results page of all the search engines on mobile, all because the addition of the favicons.
