presenter_pattern_gone_wrong?

my_presenter_method.rb

  # If the item has one comment, show it, else show the last comment and allow the user to expand
  # (yes, a slightly contrived example)
  def primary_comment
    if self.comemnts.count > 1
      "<details class='primary_comment details'><summary><h3>" + self.comments.last.text + " (and #{self.comments.count - 1} others)"
      "<ul>"
      self.comments.each[0...-1] do |comment|
        "<li>" + comment.text + "</li>"
      end
    else
      "<span class='primary_url'>" + self.comments.last.text + "</span>"
    end
  end

... which I think I figured out how to make elegant. I'll write a blog post on same in the morning.
