very good post.I'll add only the most important thing that made Betfair super big-the aggressive marketing.
Since the beginning they advertised not only on the internet,but also in all Europe,TVs,etc.Plus
they offered a 30€ bonus just like the usual european bookmakers,but without country restrictions for bonus eligibility.It was evident they lose a lot from their sign up offers (being an exchange) ,but it worked to attract customers.
They replied to every stupid e-mail asking what is an exchange,what is back and lay,etc.
