I am curious what folks do with the #show action (and its associated view)
in a RESTful application.

How often is it used?

It seems to me that, for the sorts of applications I can envision, it
probably wouldn't be used much at all.  Everything I might want to show can
be displayed by the #index action.  Is that true more or less often than
not?

If there isn't anything to be gained by a #show action, what do folks do (if
anything) to disable it?

I have seen a use for #show in the classic case of a blog, where the index
page shows the titles of each of the entries in the blog, but the user must
click on one of those titles to "show" the actual blog post, but that brings
up a related (and nearly identical) question...

I can see the same issue with the #new action for a nested route.  Again in
the classic blog application, the #show action for the post would probably
include a form for adding a comment, thus eliminating the need for a #new
action (and its view) .

What do you folks with vastly more RoR experience than I do in these
situations?  Is there a best practice?  Is there a common practice?
