One idea where you can distinguish you're in addition to being just better: add commentary/disqus and have some sort of system that aggregated and ranks comments (like stack overflow answers) on each man page. I find that man pages always have all the info I need, except it's often buried or there are surprises, but others' knowledge/experience can really save you from common pitfalls not in the man pages. Just having s crowd-sourced highlighter function of sorts would give you a unique offering among the competing options. You could also augment the see also section. And for marketing, you could have a blog and write about the top BSD tools based on activity, searches, etc, or up-and-comers. You could feature community commentary (like how to best use a tool) and build in some kind of point/reward system. I have more ideas but I'll stop there. Good luck with your project!
