Developing a social networking site part 3 - tag cloud

This is a simple one.
I use the excellent acts_as_taggable plugin, and I wanted to have a
tag cloud like everyone does.
Of course I have different Models that can be tagged, and I want to keep everything DRY, so I created a helper and put the following in the application_helper.rb file
This allows me to have multiple tag clouds for the different models, see snowdogsr.us on the left bar at the bottom.
The font is bigger for the more popular tags, and you can click on any tag to get a listing of all matching articles.
I use RESTful routing so I added this to routes.rb
map.resources :places, :collection => { :tagged => :get }
which creates a named route tagged_places_path which returns an
index with the places tagged with the tag that was clicked.
The places_controller method looks like this...
