IS FACEBOOK BECOMING BORING FOR USERS?

The expand of Facebook in few years is fantastic.I don't know if is somebody with don't hear about it and have an account.In the last period the number of the persons wich pass time in the Facebook are less they were a six monthss ago. One of the main reason is because the useres are becoming bored about the network,configuration,design. At the firs view it's no logical what i said,one of my arguments is that Facebook reach at 900 milion users,and I think it's a solid argument. Facebook are maked some changes in his desingn for one reason to attract user what it did.
