The Wired Magazine online story is Mob Rule! How Users Took Over Twitter. I found it interesting reading.
For the same kind of thing in Facebook, here’s a link to a Google search for “Facebook user revolt.”
The user revolt is a high-class problem. It’s the trappings of success. It means 1) you have users; 2) they care about what you’re doing with the site they use; and 3) there’s a forum or medium they can use to make their opinions known.
This is a great sign of real success. It’s a problem only if nobody listens.
