Keep in mind, though, that Rails 2.0 is in this respects a superset of
1.x. You don't have to use the RESTful facilities if you don't want to
(and you certainly don't have to use the scaffolding). I would agree
with Brian in spirit but I'd put it slightly differently: it's easier
to start with the non-REST stuff and then learn the REST stuff, but
all of this can be done in the context of 2.0, i.e., it's not
specifically a 1.x vs. 2.0 thing.

In training people in Rails, I definitely do not start with REST and
resources. map.resources is essentially a macro that creates a bunch
of named routes for you -- so if you don't know what a named route is,
you can only do it in a black-box and parrot-like way. Learning named
routes doesn't make much sense until you understand routes, and routes
don't make sense until you know the basics of the request cycle... and
so forth. So I would never introduce someone to Rails by telling them
to write map.resources in routes.rb and trying to proceed from there.
