Earlier quoted context omitted.
bang commands on DDG come pretty close. I use DDG as my primary search, but in reality I use about 20 different commands for specific searches on any given day, including quite a bit of google search and wolfram alpha. Not saying these commands will ever see wide use, but I find it a convenient platform for lots of different search engines.
That's a really good point. Every few months I try to adapt to using DDG as my primary search, but I always find myself throwing a !g into my searches, which kind of defeats the purpose. I'm curious, for what kind of searches do you find DDG's own search results to be good enough (or better) than Google's? What kind of searches make you bang to Google?
That being said, I end up using the DDG results for >50% of my searches. If you do more local searches, or if the things you search for tend to be noisy or obscure then, of course, YMMV.
