Thank you for your response, Michael.

The fact that I don't have a specific goal doesn't imply I'm unaware of how valuable the node editor is. I'm sure it'll be useful (I'd prefer to say "mandatory") to model recurring patterns and the like, especially if there's a lot of room for changing the object on the fly.

To acquaint myself with the tool, I'd want to doodle with it (modeling and altering recurrent patterns model).

Cheers!
