Where it usually starts
A neighbourhood of a few thousand homes talks to itself through a tangle of channels: a public social media group with members from three towns away, two messaging groups per street that nobody can join without knowing someone, a printed newsletter four times a year and a noticeboard outside the shops.
- A lost cat is posted in one group and found in another.
- A warning about a doorstep scam reaches the streets where someone happened to share it.
- The residents' association asks for views on a traffic scheme and gets forty comments in a thread, half from people who do not live there, and no way to count who thinks what.
