Note URL vs story title.

This is nothing special, nor is it an official URL. You can type anything you want there and the link will still work.

http://www.independent.co.uk/life-style/food-and-drink/this-...

http://www.independent.co.uk/life-style/food-and-drink/so-wi...

Same thing in StackOverflow:

http://stackoverflow.com/questions/5711120/this-is-not-reall...

The difference is that StackOverflow has the good sense to not display the typed-in URL.
