LinkedIn’s feed is boring and could be improved by toning down promos and likes, and introducing an easy model (User-System-Content) for evaluating recommender systems in general. Like 40% of LinkedIn users, I’m on it every day. LinkedIn has a monopoly on public CVs which are useful for lots of reasons. And many of the articles are interesting. But the rest – epitomised by the activity feed – is dull. No wonder LinkedIn is one of the least sticky social media sites.
