I won't expect a non tech-savvy kid (<18 year old) to use an online forums nowadays. Especially a forums with a 2000s layout and a lot of restriction.
Somehow this is true, but on the other hand Bitcoin in the last years is more and more about money and business so the not so TikTok style might actually help Bitcoin not to be seen as an amateur project. Still I would appreciate also for bitcointalk to have a better appearance like Reddit for example that has a growing Bitcoin community, but not even 1% of the knowledge that is represented here.
