For me there are lots of little reasons. I suppose its a personal choice.

I like the URI structure better and chained makes me think about the URI 

I prefer /item/1234/view to /item/view/1234 as it lets you add more 
functionality in an intuitive way:


and if the user just deletes the edit/view part of the uri you can do 
something sensible.

Other people in the team can just chuck a new action on the URI without 
wondering what I called my validation routine.

It prints a nice URI dispatch table in debug mode.

As I said, for me its lots of little reasons that just feel right. But 
mainly its about the URI structure.


p.s. What Aristotle said.
