Rails routes, respond_to and more

As pulled from:
http://info.michael-simons.eu/2007/08/06/rails-respond_to-method/

I've used respond_to previously...but it slipped my mind..so i figured I'd repost it here.

Here is the snippit that replaced a separate (and now useless method) for each major entry view page.

respond_to do |format|
format.html
format.js { render :partial => 'list.html.erb' }
end
