The focus of this new social media site is allowing users to join vertical networks, each with feeds that offer specific content that’s actually relevant to members of the same professional circle.
In Workfeeds, TechCrunch says, a vertical network is set up for different verticals. Currently, “Hedge Fund Investment Professionals” is the only one that’s live, but others are expected in a few days.
Most professionals are so busy they don't have time to look at their LinkedIn account daily. So even if Workfeeds is great, I doubt it can overcome the huge lead that LinkedIn has.
It's akin to the situation with Google+, where the established social media sites with millions of users can upgrade their technology and copy a startup when a new social networking site appears to have a truly unique feature.
