Hi Bez, yes we do post links to particularly interesting threads on social media once in a while - we are a social media site and depend on attracting more and more visitors so that we can keep the site going and continue to try and improve it.
Please remember that Gransnet is an open forum and anyone can view the threads on here - they don't need to be a member. We don't include any usernames on the Facebook posts, but rather just link to the discussion, usually with an illustrative quote and image to explain what the thread is about. This is something we, along with Mumsnet, have always done.
Gransnet posts will only appear in someone's newsfeed if they have specifically 'liked' our page, though anyone can go in search of us on Facebook.
