I'm fond of the communities too. I like that it means that I can post something completely of my usual genre Splinterlands and it can reach an interested audience, rather than me trying to punt it to my usual group of followers who have no interest in it. I think a lot of people have those different sides and at one point a few even started up separate accounts to keep the genres separate. Now there's no need.
That circle jerk label seems to be very liberally applied. How dare you not vote on something you're completely uninterested in! You're a circle jerker!!
And that is one thing I really hate about it also.
