I get the sense lately of Linkedin being full of recruiters and job hunters rather than professionals searching for networking, or companies trying to reach out to an audience. Facebook does indeed help with marketing a brand. But it's not aimed towards networking. Searching by a person's attributes has been stripped off a couple of years ago, and when you message a person not in your social circle the message will usually be blocked off (sometimes even if you have a basic set of mutual friends). Optimally I'd like to see a social platform that does both properly - allows you to discover new relevant people (for professionals, recruiters, job hunters etc.), is a base for businesses wanting to showcase their product and what they do, while keeping your closer circle of friends close.
