In some ways, this isn't surprising. When Microsoft bought LinkedIn, Microsoft officials repeatedly said they'd learned from mistakes of past acquisitions and planned to take a largely hands-off approach in managing LinkedIn. In 2017, Microsoft allowed LinkedIn to focus on growing its engagement numbers as measured by "sessions." LinkedIn focused on updating its feed, adding video, overhauling its messaging platform, and focusing on active job seekers instead of passive candidates.
I've spent some time combing through Microsoft and LinkedIn blog posts from calendar 2018 to find evidence of integration progress between the two companies. I found eight announcements, with two of them actually delivery announcements for integrations announced in 2017.
In 2018, Microsoft began reporting LinkedIn commercial revenues as part of its Productivity and Business Processes revenues. And the commercial portion of LinkedIn's business -- LinkedIn Recruiter, Sales Navigator, premium business subscriptions, and other services for organizations -- is now reported as part of Microsoft's "Commercial Cloud" numbers.
I don't have the feeling that Microsoft officials are dissatisfied with the integration progress with LinkedIn. They seem OK -- at least publicly -- with achieving these kinds of incremental integration points between the two. I don't see this changing in 2019. And I don't think Microsoft's top brass will be mad about that.
