So what would be the mysterious date of Facebook timeline that Facebook will officially launch for all the users - would it be October 1 i don't think as the date has already been past, or October 6, or October 13, i even it could be October 20 ? probably not.
Here is what seems to be happening that When users activate the Timeline feature from developers site, Facebook gives them a date when their personal profiles will publish. It does not necessarily refer to the date when all users will receive the feature, and varies from user to user.
The date when Timeline profiles go live seems to relate to when the profile was activated. Someone who activates today, for instance, receives a later date than someone who activated a couple of days ago.
Some observers have interpreted the multiple dates as evidence that Facebook has pushed back its public launch of Timelines, perhaps as a result of a trademark lawsuit that was filed by Timelines.com (nothing in the legal filing indicates that Facebook changed its Timeline launch date). It is more likely that the feature is intended to launch gradually rather than all at once. We haven’t discovered a launch date, because there is not just one.
