Because it won't work in every browser and making shortcuts the same across Firefox and Chrome is a hassle, plus you can never get up to thousands of shortcuts

Because it won't work in every browser and making shortcuts the same across Firefox and Chrome is a hassle, plus you can never get up to thousands of shortcuts that DDG has. Sometimes, I'm just experimenting. I had no idea that DDG had a Flickr bang because I never had the need to use Flickr before, but I just added !f to my query and I got the results I was looking for.
