I dont use FB, but I do use Linkedin - however - the comparison that Linkedin's 70 million users to FBs 600+MM users as seemingly a potential threat/issue to Linkedin doesnt account for the quality of the userbase.<p>Linkedin's usefulness does not require me to waste hours a day on the site - but it works perfectly to keep track of those who I want to keep track of.<p>I am sure that BranchOut will have a lot of users - but I don't think they will carry the same weight in the industries I follow as linkedin.
