The moves that Facebook plans on making go well beyond getting lobbyists to protect their interests. Currently, Facebook’s only public-facing interest is control over basic Internet functions – pageviews, eCommerce, social influence, and access. Facebook is already exceptional at controlling pageviews.

Their social influence is unquestioned and nearly unchallenged. Access – new websites are born every day that encourage or require logging in through Facebook.
