One of the non-music trends of 2014 was the emergence of workplace tools using the features of social networking (messaging, photo-sharing, news feeds etc) for corporate purposes. Slack was the Silicon Valley poster child for this area, raising a $120m funding round valuing it at $1.1bn. Now Facebook wants in on the space too. It’s launching something called Facebook at Work, which will use familiar news feeds, groups, messages and events, but within company-specific micro-communities, completely separate from people’s personal Facebook activities. It launched as a pilot scheme yesterday for a limited number of partners, with a website and iOS/Android apps available for companies invited to the trial. The initiative is bossed by Lars Rasmussen, who previously had a crack at a similar idea when he worked at Google: Google Wave. Facebook at Work is something to watch when it comes out of its pilot period – it could be useful for music industry firms like any other, if people aren’t concerned about bringing Facebook into their work.
