While it is a bit of an obvious concept, the guy behind about.me have made it work, as they were bought by AOL within a week of being officially launched. The idea is you create an account and you create a very visually attractive page which houses a brief bio of you as well as links to the many places you can be found online. Many social services integrate directly with the site and allow you to view content elsewhere on the web from that person without going anywhere, which is a unique extra touch.
You use a wysiwyg editor to move text and links around the page, and you have the option to upload a large picture to fill the whole screen. A lot of people decided to use this feature to upload a large picture of themselves. It helps to differentiate this service from most others because of how visual it is.
I’m not sure if it’s really going to catch on, but it is a nice idea and certainly a lot of popular people in the tech industry have got on board. Whether or not it will go mainstream is unknown, but I would hazard a guess that it will stay a service primarily used by tech and social media enthusiasts as well as some celebrities for the foreseeable future.
