I started from that thought and built True Path Finder from it, a tool to facilitate collaboratively finding the truth about what will take a person from one state to another, using a very generic method: 1. Anyone can post any goal they have, or try publicly posted goals. 2. Anyone can try publicly posted methods to achieve that goal, or post their own. 3. Users try the methods and share their experiences as reviews. Repeated reviews are enabled and encouraged, to understand how their experience changes. 4. Users learn about each other’s experiences and may find a better method to achieve their goals.
There's a mode called "My Cave" in which you can do all that but privately. Following the cave analogy prompted me to make subsequent page's background color darker, and also making it so that you can only exit the cave through the page you entered. It was fun :) I hope it helps make it extra clear when you are interacting publicly or privately with the app, since everything else looks the same.
There are also "events" which anyone can create on any method, which are scheduled in advance, people RSVP to, and have 3 phases: Arrival, Practice and Close. A text chat is enabled only in the Arrival and Close phases. The text chat is accesible only in batches of 7 to 21 people, to ensure focused community discussion and allow the group to self-moderate. If all batches are full and a group would have 6 or less people, they would be allowed in full batches.
These events allow people to ask focused questions, reflect, foster community and discipline. They also avoid long asynchronous discussion which may distract from achieving goals. There's a 21 min daily limit for using the app, to drive the point further :)
There's a guest mode available so that you can do everything except post public reviews and chat in events unless you create an account.
