I am sure that if we conducted a survey on some other forum or social media asking what forum Satoshi Nakamoto was active on, very few people would know the answer unless they are also members of Bitcointalk. But the thing is, that piece of information doesn't mean much for members who come here. Satoshi is long gone and those who register want a useful forum, which satisfies the needs they have.

If the main device they use is a mobile phone, they might take one look at this place, realize that it's quite difficult to navigate, and go elsewhere. The fact that Satoshi used to post here wouldn't change their mind. I agree with all the other points you made but would like to add that the forum's policy of not moderating scam decreases the quality of an otherwise excellent marketplace.
