The world's largest online social network, which recently broke the 600 million member mark, announced Monday that the new profile page format will now be a permanent fixture for all of its users.

"For the month of December, we gave people the option to upgrade to the new profile early, and hundreds of millions of you made the switch," Facebook engineer on The Facebook Blog. "Starting today, we'll be rolling out the new profile to everyone."

Everyone, though, isn't happy with Facebook's move--judging from the comments about Rha's posting. "Don't like it!" Bonnie Coomber, of the Cator Park School for Girls wrote. "Bring back the old one!"

"Get a dislike button," Tomasina McGinnity complained. "Not a new profile."

"Well, this sucks," Filipe Monteiro groused. "Why not maintain it as a voluntary choice?" Monica Baguchinsky Lunn agreed with Monteiro and added: "Everyone I know is complaining. It doesn't matter, tho. The fb gods have made a decision and all us little people don't matter."
