I would argue the opposite. Facebook is in prime position to move quickly and break things. They have enough traction, gravity, and brand recognition they can afford to make mistakes. If you have a small user base or are just getting started, delivering the best product experience is the #1 thing you can do for success. Is iterating faster and making more mistakes and giving the early adopters (ones that champion your service the most to others) a sub-par experience worth the speed? Sometimes, yes. All the time? No. Facebook can change your privacy settings, steal your e-mail address, recognize you automatically in photos, watch your browsing activity outside of their walled garden, and sell your data to advertisers. And yet they still have 500million+ users.
