About.me serves a simple purpose: make a one-stop, single page destination for yourself. By giving the site permissions to various API (Flickr, Instagram, Vimeo, Twitter, etc) you create a quick overview of what you've been up to. It's the simplest single page profile creator since Flavors.me (which I also love but seems to have some content grabbing issues from time to time). I made one for myself and don't expect to do much else with it but, at the very least, it's a great link to include in an email footer.
