Video: Why Email is the Killer App for the Web
As Mark said it, "email is the Killer App for the Web". People use social networking to broadcast to everyone what they're doing, but use e-mail to control the personal or professional messages and to whom are sent. Although we live on a Big Brother world, and almost everything is opened wide, some things are kept personal or inclosure.
People need to have an email account even to login to a social network. People need an email to enter to whatever system that needs to send notifications or whatever. Even one of the most prolific and high growth in popularity and usage blog system in the world (Posterous) has achieved it by having a full posting capabilities through email. Email is user friendly and people are almost born knowing how to use it. So apps are good, social networks are fine but email still rocks in usage, baby! :-)
