i noticed that on the main page, www.duckduckgo.com, the boundary box for the logo/link seems to be literally on the border of the search bar. given that there isn't a visible boundary, i doubt most users would click only a few pixels above the search box intending to go to
https://duckduckgo.com/?q=DuckDuckGo. maybe raise to just below the 'DuckDuckGo'?

just nitpicking,
