10 houses in our Close, all friendly, 6 with old farts like us, another just retired, What’sapp group brilliant for us. Anyone with a delivery due posts for requests from others. I get priority due wife’s health so often get requests for add ons. For us it all works very well. I am also the NW coordinator. 🇬🇧
These things can indeed work very well, but it largely depends on everyone being of a similar mind.
There's something like 60 houses on our little estate, and being a privately owned estate, there's a residents committee chaired by one of those self important types who makes it as cliquey as a WI stall.
He actively doesn't send out information or include certain households in updates etc* yet gets very vocal at the AGMSs about people who don't participate/sign up for or respond to memos and the like... Net result is that when things like the Neighbourhood groups are suggested, no one bothers.
*Deliberately mistyping email addresses/names etc so that they don't get delivered.
In the ten times or so in the last twenty years that he has deigned to address me, he never gets my name right, so I now call him Dave or Steve instead of Richard...
Local Facebook groups also can work well provided that it's limited to things like social get together, reporting busted street lights, has anyone seen Vera at number 17 recently? and as a local marketplace
Dad used to swear by Facebook for hobbies and clubs, but my experience of how some people use it, even in business, means that I will never sign up for an account.
