Yes social media platforms have been much more popular with the younger generations than old school forums.
Which is unfortunate IMO. In comparison a forum managed such as this one, all of the content is nicely sorted and organized. Everything can be found. With social media platforms such as FB it sorts what it wants to to show, doesn't show things it chooses not too, moves things around etc... Finding specific posts and information can be difficult and frustrating. But, opening your FB app, and having the most popular posts show up in your feed, feeds the immediate gratification that people are so addicted to. As opposed to navigating to different sites, and scrolling through forums/topics/threads/posts to find specific content.
