I got so disappointed with ddg when I discovered it's just a wrapper around Bing. With privacy-related AdBlock filters I get the best of both worlds, Google and no tracking. The world needs a non-US based alternate crawler but no one is offering it.
How about a US-based alternative that doesn't enforce UK, Pakistani, EU, and various other censorship lists that foreign countries promulgate?
