Whilst this has been written from the perspective of Building in Public which is very much a creator and founder thing. We need to understand that the Building in Public movement is really just a 'grow in public' movement.
The best builders in public, imhro, are those that are authentic, transparent and educational. It does take practice and support to get there though. It's a scary thing to do. More people would get to that point with a better support system.
Getting the attention and the following is also wonderful, but all too often it changes the vibe. The more you grow, the less depth you can have with people. It becomes something that needs to be managed.
Whether you are starting out or have been building in public for a long time, building in community can always create a valuable layer of depth and support that you can't get 'in public'.
