When applying Domain Driven Design to a project, how do you identify the Aggregate Roots?

For example, in a standard E-Commerce website, you might say that the Order is one, and the User is the other. But what if your Users belong to a Company? Does that make your Company the aggregate root?

I'm interested in hearing people's approaches to working out the Aggregate roots, and how to identify poorly chosen aggregate roots.

During many, sometimes inundating, debugging sessions using DDD, I stumble upon loops. And I keep pressing next to get passed it, and if there are many iterations, I just set a break point right after it, and press "continue." Is there any other way to go passed loops? Thanks >>> More
