I do think your post is eagerly profitable, explaining clearly what surrounds Social Media and stops in deep on the 3 major social media channels. Besides this, I’d like to expand the point about LinkedIn with this extra data:

- The average LinkedIn profiles working at Google is 47%.
- The average number of Harvard Business School graduates is 58%.
- People with more than 20 contacts have 34 times more chance of being contacted for a job that a person who has less than 5 contacts.
- In the point you mentions that Fortune 500 are represented in LinkedIn. I’d like to add that, in fact 499 of them are represented by director-level upwards.

Hope this helps

Thanks for sharing
