The world’s largest social networking site Facebook.com can start distributing mail with the extension @facebook.com at any moment. In the meeting where many people will be present, Mark Zuckerberg will talk about the innovations to be made on Facebook. One of these innovations would be about mail services. If Facebook starts distributing emails, I think it will cost a lot. After all, if we consider that many people in the world are Facebook users, and if we consider that some of these users are Facebook fanatics, this mail service of Facebook will be really popular. I think it will be kept at least as long as @hotmail.com.
