Cathedral building or its more practical and common relative barn raising are expressions of communal effort, and a monument to a community's value/coherence. What a community creates for communal use can be proxy for its meaning. It's a result from community feeding back into community. I've also used the metaphor of mushrooms on mycelium (also comparing orgs to mushrooms)

"Social infrastructure is what love looks like in public" Social infrastructure is an expression of community/communal values, and an active intervention in bringing about that community and building those communal values. Result and intervention. In community building you can use this, create the intervention and people will treat it as a result (and thus act within that community as member), Vgl [[Community building 20100210214508]] Wenger et al. I realise I never made a Notion about 'cathedral building' as a testament to community created / strength https://www.zylstra.org/blog/2010/05/working_on_stuf/ . Social infrastructure is a form of 'cathedral building', or more modest 'barn raising', where the process is a community intervention and expression, and the result feeds back into that.
