Ummmm... A few points from an admitted ORM bigot....

I would hesitate to call ORM "a dialect of entity-relationship models". ER modeling models entities, attributes, and relationships between entities. ORM models obects and the roles they play with other objects. There are no attributes, and the elementary fact concepts ensure normalization. However, the benefits of the method are well detailed in the cited websites.
The conference in Anaheim is not an ORM conference, it is the Meta-data Conference and DAMA International Symposium. More techniques than ORM will be represented there, some good and some terrible, I'm sure. It is true that there will be two presentaions covering ORM there, one by myself and one by Dr. Terry Halpin.
I would hesitate to dismiss the concepts as "yet another methodology". An opinion, granted, but I encourage you to check it out in further detail.

HTH,
Scot.
