Wikipedia has lots of disambiguation pages but somehow this idea has never made it into the search world.
Perhaps the idea of a single text box that you can type "Michelangelo" into is not a good one. Tracking the user so you can get some context (is it Ninja Turtles or art history usually with this person?) seems a logical extension of the lunacy of that situation.
I use DDG a fair bit but I feel like without revisiting that assumption that a single context-free text box is even desirable, ditching the tracking (which I am totally in favour of) feels like they are dooming themselves.
I've played a little with running Yacy locally and directing it to crawl only sites I care about. So far that habit has not stuck.
The bangs are a step in the right direction. Suggesting additional search terms isn't quite right, and neither is doing a site specific search since I don't know what site will have the information.
Maybe a "metabang" where you search all the bangs in a category? "python !!tech"
Anyway, its good to see DDG growing.
