Last week they did not.
Probably because DuckDuckGo implemented this feature and google did not want to lose the first movers (I was about to make DuckDuckGo my default searchengine)
Google is not showing balance yet, but I think that's just a matter of time.
Google will always want to be as good and better as it's competitors, so expect them to do things like this. A lot about business is less about creativity and more about pseudo-copying your competitors.
DuckDuckGo as Google's biggest competitor? Are you Joking....? DuckDuckGo has to be the Stupidest name I've ever heard.
So DDG is Google's biggest competitor that actually brings something new to the game, as opposed to just copying Google.
That may be true, however DuckDuckGo's name proabaly ensures that it will never get anywhere. That name is HORRIBLE.. They need a simple name, not something childish and stupid like duckduckgo.
