What social networks can learn from public spaces

-Are designed in partnership with the communities that use them.

-Engage stewards, leaders, and maintainers who can do the labor of community-building

-Are designed to be physically accessible and attractive to many different populations

-Offer visual cues as to what kinds of behavior are invited in the space

-Develop programming – social activities – that draw different groups in, without over-optimizing for any one group
