[Seaside] Page layout best practice

[Bill Holloway]

There exist many layouts schemes for dynamic web app frameworks.
Usually they involve a header, footer, navbar, and main content.  What
practices are seaside users using to get this?

I'm just making one instance variable called 'main' in a "border" or
"framework" component, and populating it with whatever other component
is called for via some links in the navbar.  "main" gets a blog
component if that's clicked, an "about us" static sort of component if
that's clicked, etc.  "main" is rendered via "html render: main",
naturally.

Is this the emerging best practice?
