I'm a founder of a community website. However, I still have a dayjob to support myself. That's why I build a team to help me operate the site. But since I can't afford hiring professionals, my team consists of interns and freelancers instead.
With a day job and a team that doesn't work together in the same place, I need a central knowledge base wiki to store information about the site, our SOP, our policies, etc. Since the site is still new, we also need interactivity to allow us to keep on updating the knowledge base wiki.
