As you and I both know the forum rats tend to get more rabid the longer the devs stay away. Why do they get more agitated? Largely because they don't know when, or indeed if, the next interaction will take place.
Keen Software House, for all of their flaws, had something good going with "Update Thursday". Of course, being Keen, they tried to post regular game updates at the same time which was a horrendously stupid idea and gave me no end of amusement watching the same bug get fixed and unfixed on a regular basis. Regardless of that, the weekly update thing was good, all it takes is a single sentence from each department about what they're working on, possibly the occassional amusing anectode. Do that once a week on a regular day and it'll help the community feel more included and less like a puppy with separation anxiety.
This would likely make your job much easier and slow down the rate of posts being shovelled out of the way.
