Facebook recently announced that they are going to begin a Rollout in Facebook timeline profiles and they are starting this limited work first in New Zealand and if its being success, Rollout will be spread all over the world. There is a public secret which made Facebook to begin this service first in New Zealand, Since New Zealand is a English speaking country and it will be easier to get and analyse feedback for them from users. Let us listen to words of Facebook in their blog post
“We announced Timeline in September and made it available to developers building apps on our platform. Since then, over a million people have signed up for the developer beta to access Timeline. The feedback we've received so far has been invaluable. Starting today, we are making Timeline more widely available as we measure speed and other types of performance. We’ll begin by making it available to people in New Zealand and then roll it out more broadly in the near future.”
This Rollout is a little bit tough for Facebook servers since they have to perform their maximum power for displaying the most old post from each user. Actually Facebook's aim is to allow users to manage their friends's historical activities such as the posts that they have done years and years before and this can be also considered as a work of facebook to explain the privacy consequences of Timeline very carefully. By making the entire history of a user’s Facebook activity more readily accessible. This rollout comes with a huge bonanza for developers of apps that leverage the Open Graph API that can publish content to the Timeline. Developers who’ve been prepping their apps in anticipation of the universal access to Timeline should start putting the finishing touches on so they’re ready when the rollout expands.
