Mr Nadella wants LinkedIn to become the place to go for news and other details about people’s work lives, but firms are unlikely to want to give their employees more of an excuse to spend time on social media. Some bosses regard LinkedIn with hostility because it makes money from recruiters out to poach their staff. They will not want to let LinkedIn further embed itself at their companies. Already some large firms block or restrict access to LinkedIn on their networks. Users may also grow uncomfortable if Microsoft deploys their data elsewhere and could stop using the service. Mr Nadella has acknowledged they will have to treat what they know about users “tastefully”.
