I have a question for you also, do you not think that If bitcointalk refuses to adapt to this increased userbase than it's ability to survive against competitors and continue to be the favored place for crypto discussion will continue for very long?
As far as I know, Bitcointalk is run as not-for-profit. Also, as far as I know, it has enough funds to keep running for quite sometime, even if revenue from donations and advertising stop completely. Also, since this forum happens to contain many important posts that are important to Bitcoin's history, (i.e Satosi's posts) I am certain some form of it will survive in archival form.
