I took a quick look this morning, but wasn't sure, at first glance, the purpose of the site. It looked like just links to a bunch of major sites. Please keep in mind this was 5am and before coffee. The buttons and text were a bit small for mobile.
What is the purpose of the site? Why shouldn`t i go to google, bing or yahoo directly?
To be honest, i do not see any value in that website because everybody has their favorite searchengine and sticks with it.
It would have made sense if you catch all the searchresults of all searchengines and output all of them ... Of course you would need to remove duplicates etc.
