@ vinodh timeline is a new feature..it is different from earlier profile view as there is a cover photo and a separate display picture and it shows the activities of the person according to the month.
I feel facebook will be surely over take by google plus as the demand for facebook as it is bit unsave for the information shared in it
Sarala, I guess any information shared in world wide web is not safe and facebook is very very popular, google plus will take some time to gain familiarity among facebook users.
