Handling requests RESTfully?

Question

There is a push in modern scripting frameworks to use RESTful request routing instead of a one-size-fits-all URL path routing.

respond('GET',    '/posts',       callback);
respond('POST',   '/post/create', callback);
respond('PUT',    '/post/[i:id]', callback);
respond('DELETE', '/post/[i:id]', callback);

vs

respond('/posts',       callback);
respond('/post/create', callback);
respond('/post/[i:id]', callback);
respond('/post/[i:id]', callback);

I must confess that I am still using the old-and-busted method where the resource is accessible at the given URL regardless of the request type.

Is there anything I'm missing by using the old format?
