The main thing I like about this service is the looks. It's mostly sleek and refreshingly minimal with a colorful and expressive logo to boot, a la Google.

DDG on the other hand... while I love the idea and would love to use it more often, not only gives poor results for most of my searches but the heavy use of red literally gives me a physical anxiety that makes it basically unusable. I could style the page myself but they really need to consider losing the red in favor of green or purple or gold because I can't be the only one who experiences this.
