Now that we can finally have pages on Google+, Gaming should totally get one!
Along the lines of what Dave DuPlantis said in the comments, I fully support this idea, if we can get people to maintain it. If not, I think it looks bad to have a dead page.
Along the lines of keeping it active:
If we can steal an SE dev for a while, perhaps they can patch some feeds up to automatically post, similar to how our twitter account works. In addition, we need to do a lot of the same things suggested in the meta thread about our Facebook: Post, post, post! Post good questions! Post good answers! Promote our events! Promote our servers! There's a whole host of things we can do, but with one caveat:
We have to be careful not to overdo it.
People who get bombarded with post after post about us will eventually ignore us. Remember: moderation. Find that happy medium and thrive in it.
Another thing that can help ease the burden of maintenance, is having several maintainers. It's a lot easier for 3 people to post twice a week than for one person to post daily. I think that one post daily (maybe more if G+ explodes and peoples streams get more cluttered) would be a good ratio for keeping us in the public eye, yet not so much that people start to find us annoying.
