Using ORM for conceptual modeling?

Does any have any experience using Object Role Modeling
(as in "Information Modeling and Relational Databases" by
Terry Halpin- supported by Microsoft's VisioModeler)?

I'm curious what practical experience anyone has using this data modeling method/language versus ER or UML, and in which cases ORM would clearly be worth the learning curve
(and need for later mapping to a logical model/schema). For
example, would ER or UML (class diagrams) be better suited for a simpler project/problem space, whereas ORM would be better suited for larger, more complex problems...?

thanks for any input,
