"to provide for Progressive Trust, you need to establish what is known as an "Intimacy Gradient"". From architect Christopher Alexander's "A Pattern Language: Towns, Buildings, Construction:
Pattern #127 - Intimacy Gradient:
Conflict: Unless the spaces in a building are arranged in a sequence which corresponds to their degrees of privateness, the visits made by strangers, friends, guests, clients, family, will always be a little awkward.
Resolution: Lay out the spaces of a building so that they create a sequence which begins with the entrance and the most public parts of the building, then leads into the slightly more private areas, and finally to the most private domains."
Hence, in any house, "there are always some areas ... more public -- the entry, the living room... and areas that are more private such as bathrooms... In a good design there is some marker of change between these different areas", otherwise "uncomfortable buildings".
A software's design also needs an Intimacy Gradient, as do communities, with different levels of privacy/openness. This is hard online, as every page - no matter how intimate is should feel - is equally far (one link) from every other page. Potential solutions from architecture include:
