I'm 44 and assumed I was one of the older ones but clearly not!I like exeweb for this exact reason, it's like a time bubble from mid 2000s, same names to argue with until the end of times, love it. For a few years I thought Facebook groups might take over but the decline of that platform and low quality debate brought me back here.
I'm 36 in February and often considered one of the younger ones, which says a lot
I have teenage kids and the last thing they want to do is post on forums, they literally cant be @rsed. As Ant says, tiktok, insta, possibly twitter is more their scene, I'm not even sure if they know what Facebook is, that's definitely for the over 30s.
