You consume way more content ON Facebook than you are aware of. Thats the big difference. And a lot of content is being written ON FB. The discussion is ON FB and they allow them to be long which keeps people there too.<p>Just the ability to do a preview of on article is such a big eyeball keeper that it leaves twitter in the dust. Or to write a comment to the article which make people then react to what someone wrote about the article without maybe even reading it.<p>It&#x27;s like with checkins. People think FourSquare and Swarm is big but it&#x27;s dwarfed by FBs checkins it&#x27;s just not a major focus for them and so we don&#x27;t think about it as a place a lot of people check in. But it&#x27;s a numbers game.
