Researching for a current project (which is very exciting and should be able to talk about it a week or so) I came across Front Porch Forum.
It’s a brilliant idea to help bring local communities closer together. Quite simply it provides an email list server for local communities. Neighbours (or just neighbors at the moment as it’s a US service) can sign up to email each other.
It gives an example of one community with 348 households, where 324 had signed up. The average number of messages was 20 a week with 98% of members skimming/reading every post.
I’m thinking that for someone with just a bit more techy knowledge than me, we might be able to pull something similar together for the UK. The stumbling block might be access to post code data. Any volunteers?
