Google + is now the hands down absolute best place to talk about RPGs. Pretty much almost no matter what you're doing with them.
After a little more than a year since the mass immigration, it's all good: High signal, low noise, trolls and backbiters die fast, people with different ideas crawl out of the woodwork every day, new ideas come out of nearly every discussion, it's kinda amazing.
And by "amazing" I mean "way less boring than the internet is supposed to be".
You can put up almost any idea and get useful new ideas back, mud-slingless. Almost all of the most well-known game designers post there and have actual conversations that actually go unexpected places and they can have them without any droolers showing up.
Thing is, it works on a nonhierarchical, no-boss, no-mod. social-link model. In simple terms: if you bore people, you're out, you can't even read the good stuff any more, much less comment. People with nothing to say are just left looking at each others' cat pictures, where they belong.
Now trolls and jackwads all have some things in common:
-They bore people and get blocked.
-They have an insane compulsion to talk even when no-one's listening, cares, or gets anything out of it.
-They do not consider themselves trolls or jackwads. Or at least not so much that they can understand why nobody wants to talk to them.
Which suggests the following thing is going to occur: all the RPG forums which aren't Google + or aren't on a similar social opt-in model are all going to get worse. Because the major reason to go to them will be that nobody on G+ is circling you and nobody wants to hear your ideas.
Which is nice, in a way, as it centralizes things while linking them, but Google + is not a very good gateway for new gamers--people who are not playing yet but are curious. They'll more likely find the blogs and forums.
There probably is some tag or group on Google + that sees itself as the gateway to newbies into RPGs but so far I haven't heard of it, which is a pretty good indicator it isn't easy to find or know about.
So....someone should get on that.
Oh, P.S. Google + tip:
You need to have an "inbox" and an "outbox." Anyone who posts cat pictures goes in the "outbox" and they can read your stuff but you never read posts in your "outbox" unless you're really bored. Just log on and read the "inbox".
