We're currently building a tool, which uses Linkedin API, and I performed a fair amount of customer interviews about their use of professional network and, well, Linkedin. A popular opinion of what I've heard is "Linkedin is dead", cause it's very old-school and not flexible to adapt to changes. People use it for just adding contacts, sometimes randomly, and then they rarely do anything with them. Recently they announced the restrictions to their API program, meaning that new cool tools, which try to make more sense of Linkedin data, will not be able to use Linkedin data anymore. I guess, that will make it even more unpopular for users.
