Thank you, that was some awesome feedback!

1. No worries, this topic in question just makes the concept somewhat recursive. I think it will work better in future attempts.
2. I will try your suggestion. I'll notify you when I'm finished.
3. This I will try too. I get it is a "best practice" to reiterate the benefits.
4. I noticed this too. Nice people came to say "hallelujah", but took little action. I guess the concept will work a little poorly until there is a possibility to follow people or topics, but I will try to provide some clear call to action and the way to do it.

Please try this yourself too if you write an article or opinion.
