About.me offers you to create an online profile. It can be used as a point of reference to quickly introduce yourself to strangers across the inter-web. You can mention your information, skills, interests, profession, hobbies, etc. You can even link to your social accounts on other social networking websites such as facebook, twitter, or google plus.

However, apart from the cool templates that it offers there is not much difference in an about.me profile and google profile or a profile elsewhere. Perhaps the cool about.me/username thing might attract people. But in the long run the website does not offer anything unique for people to stay on it.
