Okay, so my idea for a way to promote one another, previously submitted here , may not be the best. I have another. I find brainstorming fun – and we all should more.
Rather than tagging others in comments, Just think of any three of your fellow Personae you'd be willing to tag in a post and share with the Whole, Entire, World. Then do so.
Put up one post each, about any three of the people you follow. Tell others about who you like and why you like 'em. Believe me, this nearly built a close community on the old AC format, pre-Yahoo. It works.
Each person you post about, now, you get to friendly-goad into also doing posts about two or three others too. As each person posted about, tells about at least two others each, soon, millions of posts about the awesome membership of PersonaPaper are famous.
