A pattern to build a high quality community: a sublime mess that is public at the entrance to the community.
A high taste thing that looks messy
People who don't look closely will not pay attention because it's messy.
But the people who take the time to look closely will find a thing that blossoms in quality the closer they look at it.
The opposite of a gilded turd.
The most engaged and savvy users will self-select into the community, building high-quality momentum.
You can hide in plain sight, and allow a motivated audience to select themselves into the community.
As the community grows, it will pull in more high-quality participants even more strongly.
