There is almost no documentation out there on how to use Arguments and Relationships in Views 2, so that would be an enormously useful show topic -- which would no doubt dominate Google search results on this subject.

Or if you want to make the show more general, go through the concrete examples of how to build some useful views. When I am learning something new, I find that the recipe of how to do something is much more useful that the theory behind it.

As near as I can tell, there is almost no documentation for learning how to use Arguments in Views 2. So I wanted to start a thread of useful links for learning Arguments.

Here is what I have so far:

Logrus's Views online help

Views 1.x Documentation
This is all for views 1.x, but it looks like most of it still applies
