This is a great presentation of the feature and a good directory to learn more about the bangs available. I use them all the time, usually regarding programming topics (language reference, GitHub, etc.), but now I see there are many more I could start using. !astock for Adobe Stock is just one example. Great feature! (I have DDG as my default in Safari so searching and using bangs is a breeze.)
