Large scale adoption can become a burden to your own progress.  This is where Facebook is at this time in their evolution.  They've become so successful and so widely used that the innovation that helped them become successful is now at risk of being squashed by the very users that have flocked to their innovations.

You see when you have 175 million users, all of a sudden if they don't like what you're doing, new changes in feature sets, changes to how you want to manage data, changes to how they treat advertisers - all of it is at risk of being dictated by the very users that Facebook has courted to their network.  Facebook may think its their network, but once they get so big that "everyone uses it" all of a sudden everyone wants to tell them what they can do.  In essence Facebook becomes hostage to their own users.

If their users don't like what Facebook does, they complain to the FTC, the FCC, their congressman, each other and anyone else who will listen.  Seems kind of unfair doesn't it...
