Dynamic Short URLs

The idea is to make a url shortener with custom backlink (which is already done my many services). The custom backlink will comprise of 2 parts, one unique and the other is specific to the content it points to.

So for example,

http://somedomain.com/pewdiepie/latest will point to the latest video.

Unique Part: pewdiepie

Part specific to content: latest

Now when a new video is uploaded, this above url won't change but the one to which the above url points to will change.

The Problem that this is trying to solve is URLs aren't human readable and not at all memorable.
