I get what you're saying regarding the Youtube thing. I recently started interacting over at Twitter and was surprised just how many people apparently really into crypto (judging by their avatar, description and tweets) were oblivious to BitcoinTalk!
That is true, and especially younger people never even heard that Bitcointalk forum exists, and I am just hoping they won't get evil fee welcome message when they try to register, or they will consider it a scam.
It's something that I recently brought up to theymos. Not for marketing anything, but IMO it should be used for more than to Just inform people of outages. Plus, it would help bring some new information about this place out there.
I am all for activating twitter account with weekly or monthly news and interesting posts, and creating bitcointalk youtube account is a good idea, but youtube censorship is getting more strict every day, and I remember how they banned bunch of Bitcoin content before.
