I am not that up with apps etc.
But I do know that most young people do not know what a forum is, or a message board, or a bulletin board.
If you google forum, you also get live meetings as in a government, or medical forum etc.
I have mentoned this on other threads and other forums, as to how we can get new members.
I am an older guy, and If I start a new hobby or interest, I always search for any forums on it.
But young ones will probably go to FB or YT.
They will not search for a forum, if they do not know what a forum is.
