It seems like a good concept, the search results of Google, Yahoo, Bing, and Ask all rolled up into one engine. Yet the site is currently ranked 2,456 on Alexa, and simply by using it I can tell that the results are mediocre, and other than Ask, all of the search engines it gets results from are better as stand-alone. Any idea why it's not popular or why it's results aren't as good as you would expect?
