Social Networking Overtaking Email

It seems that Social Networking... especially websites like Facebook seem to be taking over internet mailing by storm. Social networking has now become more popular than e-mailing. With almost 67% of users preferring to use it for sending instant messages and even mails, than email itself, the social networking trend has significantly gained popularity. Thanks to networks like Facebook (one of the leading websites on the social networking front) recent studies have shown a great increase in its users in the past year. And why not... Facebook is easy to use, interactive plus everyone just replies to you on that rather than to your emails that generally rot in their inbox :s
