A list of links is a very common pattern in the web, and we use it in many places. Here we're applying it to one of the most simple ones; the help page. Generally speaking, I'm not a big fan of helpers, but there are methods which IMHO qualify as helpers when: * They do not deal with application objects but mainly strings and arrays * They return text or an HTML tag * Their logic is simple and splitting it into several methods is not necessary Many Rails helpers, like `tag`, follow these principles.
