Also not working for me if I search for some random street address (which works well on Google), even if I add a zip code to the end. Even if it isn't possible to be confident enough to show the map first thing like Google does, at least adding a map tap on any search that looks like it could possible be interpreted as a map would be cool (though I could fairly easily just add !map, so it isn't that important).

Edit: tried a few more and some of them work. It seems like intersections may never work and some addresses don't work.

Other suggestions for DDG:

Speaking of !bang!, did you consider making the tabs !images, !video, etc.? That might help more people discover that really cool feature that I didn't know existed until folks here mentioned it (and is why I switched to DDG as my primary search engine). Similarly, the "try these other search engines" section at the end could have !g, etc. in parentheses.

I'd also suggest keeping the X in the search bar visible all the time, at least if the page is wider than some minimum width.

I like the few orange lines at the top of the page as the only header to make it easier to identify the page. I just noticed the up arrow off to the right when scrolled down, which is helpful too.

I really like that you just show the site rather than the full url until I mouse over that result.

The one thing I miss is the longer text list of meanings; only being able to scroll three at a time isn't fun if I'm looking for number 11, but before it was easy to pick out #11 even if I had to click once to expand the results.

Edit: I just noticed the result site favicons, which is nice too. I don't remember if that was there before, but I hadn't explicitly noticed it. I use the FaviconizeTab extention on Firefox so I appreciate wider use of favicons :).
