We Never approved the Timeline in the first place but Facebook never got that message I Guess and you can View the Facebook Pages Introductory page to see how that will Impact your Page ..
I dont dislike the Facebook Pages new Look but I just recently got a face lift of the Hackology Page by a user of my Site, Asif Ali so I guess I wont Switch that early any time soon .. but new things are in the store:
Brand your Page
Add a unique cover photo and showcase your most important news on your Page timeline.
Highlight what matters
Pin a new post to the top of your Page each week so people notice what’s important.
Manage everything in one place
See and respond to your recent activity and private messages right from the top of your Page.
And 30th March
is the Mass roll out date for all the Facebook , so I guess enjoy the last one month with it :p
the big names are already on the Transaction and yes this new Time line renders all those Personalize Tabs kind of useless .. well they work but not in the same good way ..
