It's not perfect yet, but I'd really like to get there: http://www.gabrielweinberg.com/blog/2010/03/hack-hack-go.htm...

Here's what's coming:

--Stack Overflow, man pages & programming documentation in 0-click.

--More programming !bangs; I've already added a bunch but would love more suggestions: http://duckduckgo.com/bang.html

--More goodies; I've added a lot recently (color codes, regexp, more advanced math to wolfram alpha, today unicode); again, suggestions welcome: http://duckduckgo.com/goodies.html
