I tried (very hard) to switch from gulag to duck duck go. The one problem I couldn't get past was that the search results appeared to be compiled by a flock of autistic ducks.
This is a rather serious problem in a search engine. Maybe it works fine for "Who invented the airplane". But most of my searches are on highly technical topics. Thus for example a search on "most efficient in-memory sorting routines in Swift" will return such useful hits as "Foods to swiftly improve your memory" and thousands more of equally unrelated gibberish.
Free Association is a powerful tool for psychiatric analysis. In a search engine, I haven't seen the benefit.
I REALLY want to stop using google. But duck duck go makes Bing look like they invented the internet singlehandedly.
