I see WP sites-enabled by membership plugins to protect some of the content are growing. What is your opinion on paid communities? Are you ok on paying a fee to join them?
For a while, Facebook was experimenting with paid groups, but I haven't found any recent news on that. Maybe a failed experiment.
People seem to be ok on paying $5 a month to receive a good newsletter. Would they be ok with paying $2 a month to be part of a good community?
We are preparing a community platform that allows you to create a community and receive 100% of the monthly subscription directly into your Paypal. Not cut taken by us, but a small fixed monthly fee. We plan to build on the open if we do get any traction.
