I wonder why DDG bang search is praised like its a first time phenomena ? What ? ... did people live in a cave all this time ? It existed for more then a decade all around. Some examples include early Opera, chrome, vimium plugin, Surfraw (linux CLI search tool) etc... Anyway, DDG is refreshing. You can even turn off adds in the options. Google may be a great search engine but as far as I am concerned, it can delete 'don't be evil' phrase from its mission statement.
