From Rich Millington, in his post “The Tragic Story Of Hyperlocal Communities“:
If we want to build hyperlocal communities, we have to change the way we think about them. This isn’t a technology problem to solve (Facebook-style). Enabling everyone to start a hyperlocal community wont make it happen. This isn’t a content problem to solve (local news style). Pulling in RSS feeds and encouraging user generated content wont solve the problem.
What we need is a genuine community building approach. You identify your first members, initiate discussions, invite members to participate in those discussions, write content about what’s happening in the community, and repeat as you grow.
