Microsoft’s Socl social network is expanding to mobile devices this week. After originally launching in late 2011, Microsoft’s Socl experiment has been confined to a browser over the past couple of years. New iOS, Android, and Windows Phone apps aim to change that somewhat, with touch-friendly controls for smartphones and a focus on the top mobile operating systems. Unfortunately, the apps are simply web wrappers based on the mobile browser version of Socl, and offer little extra benefits over the existing mobile site. Microsoft appears to have done the bare minimum on each platform to release a compatible app.
