We tried a number of single-threaded efforts to meet the challenge. We rolled out features one after another, such as a recommendation engine for people that our users should meet and a professional Q&A service. None of them worked well enough to solve the problem. We concluded that the problem might require a Swiss Army knife approach with multiple use cases for multiple groups of users. After all, some people might want a news feed, some might want to track their career progress, and some might be keen on continuing education. Fortunately, LinkedIn had grown to the point where the organization could support multiple threads. We reorganized the product team so that each director of product could focus on a different approach to address engagement. Even though none of those efforts alone proved a silver bullet, the overall combination of them significantly improved user engagement.
