I cannot believe I'm asking about this, but here we go: *When to do it (is there a threshold for # of readers/followers on social media/rate of engagement/email list size *Care and feeding of your readers (What to post/how often to post without cutting into writing time.) *Avoiding pitfalls (too much time in the group/responding, feeling too available, common mistakes, etc.) *Alternatives ideas if the idea of moderating a group sounds like too much (adapting the ideas for social media?)
