I think LinkedIn really missed the opportunity to change the way our culture thinks about work and professional communication.<p>Another commenter called LI a glorified resume service, which really nails the point. Resumes from 20 years ago are no different from the current LinkedIn profile; the only incremental signal is the connection base...and that&#x27;s only a signal if that information is public.<p>The fact that LinkedIn&#x27;s big revenue draw is simply recruiters paying for access to the full network is really indicative of the lack of creativity in changing the paradigm of thought around professional networks.
