With 950 million members as of July, LinkedIn is poised to soon have a billion users, joining a rarefied three-comma club with the likes of Facebook, Instagram, and TikTok. Started in 2003 as little more than an online repository for résumés, the Microsoft-owned behemoth has recently transformed. Not only are there more users to post, but they're posting much more often. The number of LinkedIn posts grew 41% from 2021 to 2023. But it's the content of the posts that's shifted the most, turning LinkedIn into one of the world's strangest social networks.
