Try to be consistent and deliberate with your whitespace. You should have 0 or 1 line of whitespace between lines, no more than that.

Example:

```ruby
describe UsersController do
  render_views

  describe "GET to #show" do
    let!(:user) { FactoryGirl.create(:user) }
    
    before do
      get :show, :id => user.id
    end

    it { should respond_with(:success) }

    it "assigns the user" do
      assigns[:user].should == user
    end
  end
end
```
