I set up a Google-plus Community about Cleveland!!
There were two existing groups, but neither seemed well-moderated. Both were full of ads, and mostly by the same businesses over and over. There wasn't much posting, and each had only about 40 or so members. There wasn't much good content.
So I modeled my group after the successful Washington, D.C., group which I had moderated. I'm populating it daily with news, articles, photos, and the like.
Hopefully, it will take off.
