I, too, switched to DDG, but sadly my most used bang is !g because in 1/3 cases DDG doesn't find what I am looking for.

Does DDG learn from what people !g for?

If that information isn't personalised in any fashion and the data are retained for a minimum period, I'd be OK with sorting out what types of queries aren't satisfied on DDG itself.
