I have made 7 figures from LinkedIn. It took me about 2 years to figure out the right formula. So I am sad to see such articles when I know me and many of my friends are killing it on LinkedIn. If I may, it isn't about vanity metrics. It is about the quality, not quantity. Example: for one client alone I can generate $500,000. So I don't need 1,000 likes, only the one like that brings me that customer. See? Best of luck with your blog and sorry you didn't get what you wanted on LinkedIn.
