In case you do not follow the comments on my blog posts, here’s another great one about moving the behaviour from the endpoint by Michi and my response (almost agreeing! 🙂

Of course I am not suggesting that we completely move to a world where all applications are built using the principles of service-orientation; only where it makes sense. There is always going to be a place for object-oriented design and applications.

Behaviour and semantics can be decoupled from endpoints and, instead, captured by additional metadata (e.g. workflow, semantic languages, etc.) where it makes sense.

And of course, nothing is new. We are just trying to clearly identify the differences between S-O and O-O and document the potential advantages/disadvantages.
