DuckDuckGo Billboard Ad

Duckduckgo is getting quite popular these days because of their 100% privacy search. As it is really hard to get such feature with google. You'll find that duckduckgo is taking shot on it's prime competitor. As they're fetching data from bing, yahoo that makes it ahead of them due to it's built in algorithm. So duckduckgo has the only competition from google. 

I'm not surprised at their ways of promotion via forums, banners (even billboard one) and some other methods. They're good at what they do and should get appreciation. I like the banner ad of duckduckgo, it's huge and explains why you should use their search engine.
