This is a most excellent place for technology news and articles.
Ecosia is similar to DDG but maybe better. Personally for me, I like that Ecosia gives you the option of Bing or Google for maps, while DDG just dumps you into Apple Maps. Ecosia uses the same tags, eg !g for google, but they also do stuff with trees or whatever.
Ecosia's search itself is through Bing, just like DDG.
