I received a letter addressed to my house number, supposedly from a "Lawrence Singha, Victoria Road" — no other details given. (Such a paucity of information makes me immediately suspicious!) I expect it's part of a neighbourhood-wide mailshot, so most of you have received a similar letter, or will do shortly. It's pushing a website and mobile app for which you have to register (the registration code in the letter matches your house/flat number, so they know where you live), acting as a community hub for local contacts and information, and of course, it's "free".
I'm writing just to say that, whether the site is good or bad, it's a great way for a company to find out a household's interests so it can sell you as a commodity to advertisers—perhaps rather than being "free", they should be paying people to subscribe.
