We reported on this when it was being tested, but Facebook has now officially launched its Pages Feed feature – a way for users to see a feed purely composed of updates from Pages that they’ve Liked. It’s unlikely to dampen down the rolling arguments about how Page posts are surfaced in the main Facebook news feed, though. More interesting, though, is another new feature on Facebook’s mobile site, which will soon be added to its iOS and Android apps too: a Share button. This finally means Facebook’s hundreds of millions of mobile users will be able to Share links and posts (including those from Pages / artists), matching the feature on the web version. With an increasing number of people using Facebook predominantly on mobile device, this too could boost the reach of interesting Page posts.
