Most social media websites give you an individual profile page alongside the option of befriending other site users. The adding of someone as a ‘friend’ on a social media website is not just an empty gesture. Usually when you add someone as a friend, you’re giving them greater access to you through the social media channel.

For example, some Digg users set their message inbox as ‘friends only’, so you can only ’shout’ or communicate with other users through the site when they have added you as a friend. Only when someone on Twitter ‘follows’ or adds you, will you have the ability to send them private messages or view his/her updates, if they are protected.

In sites like Facebook, adding someone as a friend allows them to see more of your profile (depending on your settings). Befriending users on Youtube allows you to follow their rating and favoriting on videos, while also allowing you to more easily share content with one another.
