Using a social “tool” is not enough without first identifying the behavior of your fans AND, just as important, the behavior of your fans as 'users' in a particular environment.

Each of your tips are great, but I'd highlight the first as being critical to not overlooked. Time spent defining a content strategy specifically for your newsfeed that articulates not only what you want to “talk about”, but your users AND you/brand are getting out of it, makes the process easier to manage and more effective at the end of the day.

I also think that having a brand personification, in this case Dave himself, participating is the experience adds to the experience on so many levels.
