"So, my friend Joe goes, and he checks into Starbucks. That will appear on my news feed, and I may or may not see it, and what we've seen is that a lot of impressions do get lost because there's so much content coming through. Starbucks can come in and say, 'I want to promote check-ins to our locations', so when I come to the site, I see a story that my friend checked into Starbucks. Now, I can click through. I can like the Starbucks page from that story, and when I like that page, it creates more organic content."
