As an extra explanation—maybe a small percentage of people are bloggers, period—be they elite mathematicians or groups that are more stereotypically online, like programmers, Finns, libertarians, assholes, etc.
I’m not sure you’ll find many more blogs by elite mathematicians than by other equally small groups, like piano repairmen, frisbee champions, etc.
Surely this partially accounts for the phenomenon. But I didn’t mean to claim that elite mathematicians are unusually unlikely to blog: what I meant to convey is that they have the most to offer (mathematically), so that the opportunity cost (to the world) associated with them not blogging is highest.
