DAILYMAIL.CO.UK - Jan 13 - A small group of Facebook users have been offered the option to switch to FB5. The major new redesign features a brand new layout and improved privacy. The overhaul was originally announced last April at Facebook's annual developer's conference in San Francisco, where the company explained some of the changes it that would be coming. The new update will also see the widespread release of Facebook Dating. The Dating feature will let users create a list of 'Secret Crushes,' and when two people match they'll be prompted to message each other, similar to any other dating app.
