In 1999, three portals – Yahoo, Lycos and Excite – dominated. Today, one stands. What saved Yahoo? Yahoo Mail. How? Mail is sticky like your phone number: you rarely change it. Abandoning your email is like you skipping town and not telling your friends. Of all yahoo.com visitors, 50%+ use mail.yahoo.com. You check email everyday. Yahoo pulls you to its other services.
How is Facebook stickier than email? Facebook is email, plus more (a lot more). You use Facebook to send friends messages. Facebook Inbox will become your spam-free email – only Facebook can do it because all your friends are on it. You trust it with your personal information, photos and friends. You use your real name and connect with friends doing the same thing (unlike MySpace). Abandoning Facebook is like you flattening your house, burning your photos, changing your name, skipping town and not telling your friends. Yes, Facebook is that useful. (Facebook users, anyone disagree?) That's why 50%+ users return daily. Facebook's network effects make it impossible to duplicate their network. Facebook is the phone number you will never change. Facebook is built to last more than anyone. Now, which do you think is stickier?
