@Tom Another voice for the G+ communities. There's really a ton of RPG talk over there. ("G+ Tabletop Roleplaying Games" has over 28k members!) There's also some great Discord and Slack servers.
@Tom A lot happens on Google Plus but the platform encourages cliqueyness; you have to know who to follow to get to the good talk
Yeah the same thing happens on Twitter
