Is Your Community Manager Your Admin, too?

We're running lean and mean in our online community. Our community managers do double-duty. Not only do they have responsibility for developing their online communities, but they serve as admins, too.

It's really not difficult to do the admin tasks needed in our social media software (or social business software, as Jive calls it). But I'm starting to wonder if there's wisdom in dividing to conquer.

The skills and traits of a successful community manager don't necessarily map over to those of an ideal administrator. Would we be better off splitting up these roles?

How do you do it in your community?
