Live check-ins is a dangerous thing to do as some have unfortunately ended up dead because of it. They get tracked through their location sharing. I've always wondered why this feature is available on social media platforms, the downside far outweighs any upside coming from it. I think it's a natural progression to be so involved in something new only to be later be less involved when the newness has disappeared. It's been a long while since I last logged into Facebook.
