Bogleheads gather at chapter meetings and conventions. And their website, bogleheads.org, gets 1 million visits a month from people discussing everything from I bonds and options to the merits of being a landlord. Debates range widely, but the focus remains constant: spreading Bogle's philosophy of simple, low-cost, diversified investing.
