SurfTail
SurfTail makes it easier to find what you want on the web by following those who have gone before you. The tails of surfers are updated in real time so you can see exactly what blogs or sites are currently related to the one you're reading and as more people follow the link it reinforces and maintains it.
As surfers find their way around SurfTail enabled websites they leave a trail that you can follow. You can see how many other people have been looking at the same site and what other sites they have just been looking at, the more visitors that have gone to the related site, the higher it is in the list.
Every visitor to a SurfTail enabled site is tracked by a unique identity, this unique identity is then scrambled in our database so that no personally identifiable information is stored about any of the visitors, it doesn't even use cookies!
