I've taken to using DDG and !freebsdman when I want to look up a manpage when GNU doen't feel like providing decent manpages.
Except I do it from the commandline, using a script I wrote called `duck` which detects which text-based web browser you have and turns the parameters into a DDG url. It also converts periods to bangs, so you don't have to quote or escape the bangs from the commandline.
So it looks like:
$ duck .freebsdman sed
