DDG's usability has always been a bit of a problem for me, it feels more like a perl wrapper over some search bookmarks than an engine in its own right. Will give this one a go for a while, there is literally every reason to try and few reasons not to.
edit: holy crap Brave, c'mon, 13 CSS files and 15 JS files for the search result page? Cold cache case absolutely matters when you're trying to grow, sort it out!
