Consolidating Controllers and Models

I have created a sample blog following the guidance provided in the
related Rails screencast. As a standalone application, it works
great. However, for integrating with other things I really don't like
having 2 controller/model pairs named 'post' and 'comment'
respectively. The names are too generic and may conflict with other
things that I want to do. Of course, the obvious solution is to
simply use other names such as 'blog_post' and 'blog_comment' and
maybe that's the best thing to do. However, it occurs to me that the
'comment' controller has only one very small 'create' method in it
which I think could easily be consolidated with the contents of the
'post' controller into a single 'blog' controller. I'd like to do
something similar with the with the 2 model classes; but, I think
that's going to be a much taller order. If I could somehow wind up
with the model classes being addressable as something like
and blog.comment that's probably what I would have in mind but I don't
know how to do it and I'm not sure that it's worth the effort.

Anyway, my question is this: Is this something I should pursue mostly
as an academic exercise; or, should I just forget about it? If I
should pursue it, are there suggestions on the best way to deal with
the models?

Thanks for any input.
