What happens if every resident on your street participates in your online community?
Wouldn't it improve the value of your community? You could borrow a ladder, bulk-buy products, sell unused goods, arrange BBQs and tackle troublesome neighbours much easier.
This is the best community you can create right now. Begin a place for members to chat, s, to give their opinion on issues, share their advice and for newcomers to introduce themselves. Now distribute a few leaflets. See what happens.
It might flop (don’t worry, there are other streets), or it might make your street a better place to live. If you have so little to lose, and so much to gain, you should try it.
