I'm wondering if anyone can explain the business concept of Facebook not displaying interesting content on the homepage for non-logged in visitors. I think displaying such content will help to lure more non members to register and explore the site fully. Don't you think showing trending members on the homepage would be great? What about the most shared links, photos and posts? Personally, I believe showing some of these content would be better than just displaying sign up/login form to non-logged in visitors. That's my opinion anyway. What do you think, friends?
