The quality of manpages can vary significantly, however many of them are excellent. The Git manpages stand out; most of the system manpages for OpenBSD are excellent as well.

One other nice thing is integration with an editor. I view manpages in emacs, and can yank the snippets directly into my other buffers for extra convenience.

i use the curl and rsync man pages weekly, if not daily for a stretch, and they're great.
