The document compares Facebook and LinkedIn, discussing their differences in users, perceptions, monetization strategies, and suitability for different goals like brand awareness, driving traffic, market research, networking, and thought leadership. Facebook has more users focused on images and conversations while LinkedIn has fewer users seeking business connections and work history. Both can drive traffic but LinkedIn relies more on sharing from business pages. Their best uses depend on targeting consumers versus recruiters and whether the focus is on community or resources.
