How valuable are Google+ Communities in terms of gaining exposure for your channels and your videos? Any tips?
Yes, but at the end of the day, most social media is just a waste of time.i personally believe all the social media outlets are valuable, however some more than others, for example facebook gets moer traffic than google + however even if you get a ratio of 10:1 between facebook and google + that 1 view like or subscription from google plus is as valuable as facebook, twitter reddit .... etc.
Pretty much this. I have my settings so they automatically share new uploads to my Google+ page, but it has been a while since I've actively used it! Still, this has been a pretty solid reminder, so I'm gonna go do the thing now!You will get an occasional plus one which is nice. And you will reach people you could not otherwise. But many communities are just dumping grounds
