I think it would make a lot of sense for the site's staff to be active in community interaction, so that there's a close knot rapport between the owners/staff and the rest of the community. It's kind of something you pick up in customer service -- if you run or work in a small store, you end up gaining a rapport with your group of regular customers, and you end up getting a reputation as being someone who cares for your customers rather than just some guy who works at a store.
And, needless to say, not everybody gets along here. A good number of staff, 4-5 or so, would be good for, you know, not alienating any number of people on here, so that there's no reason for people to, for some reason, dislike EVERY member of staff. It would be good, because it leaves people with, at the worst case scenario, at least one member of staff to turn to if they need help with something.
