I have been trying to research this with little success... is it acceptable to lazy load stuff pretty much whenever possible? Is there some drawback to using lazy loading for the majority of relationships other than making the app a little more chatty?

Anybody have any links or opinions about where lazy loading is appropriate?

Java Hibernate people recommend using lazy-loading by default. In Hibernate 3.0 it's the default setting now if lazy="..." isn't specified.

Lazy loading is used to avoid loading linked data (<many-to-one> or <one-to-many>) when loading an entity; the linked data will be loaded at the first use (if the session is still open).

So you should use lazy load when you know that you can use an entity without its linked data.
