It's not significant. In the world of search engines, you need to be the #1 or #2 player to earn major revenue. People aren't gonna wanna waste any time/energy advertising on your platform if you're getting just a handful of searches per month for say... mp3 players or cellphones. DDG is just betting on an acquisition, but it's just a wrapper around the Yahoo BOSS API.
Nothing starts at #1. Expecting DDG to displace an oligopoly built over a decade and a half in a year or two of existence is asking too much of anyone.
