How do I use fetch?

name is a node attribute, intro is an content object attribute available on the 'data_map' property.
short: intro has a much more complex structure, it's an object, not an string, and how you output an attribute's content depends on the attribute type (string/ int/ xml/ options...), so instead just use:

{attribute_view_gui attribute=$node.data_map.intro}

If you want to customize how it is outputted, turn on debug outout and site.ini[TemplateSettings]ShowUsedTemplates=enabled to see which template is used. In this case it will be <something>/content/datatype/view/<something>, and you'll be able to either copy and modify the template code instead of attribute_view_gui line, or override the template if you want to do it globally (placement override) or given a set of conditions (override.ini override).

Edit: in your specific code, use "$article" instead of "$node".

You should do as André said and enable debug information and use |attribute(show, 1), its a great help to see your node identifiers and the data_map identifiers and data.

{def $random_articles=fetch('content', 'list', hash('parent_node_id', 72, 'offset', rand(0,4), 'limit', 1))}

Using 'list' will get the child nodes with object data and as André said you need to access the data_map.

Inside your foreach loop you can do this:

{foreach $random_articles as $article}
<h3>{$article.name|wash}</h3>
{$article|attribute(show, 1)}
{$article.data_map|attribute(show, 1)}
{/foreach}

Then you will first view the node attributes and data and then the object data_map attributes and data.

Make sure you have the correct identifier name (intro) as well from the class file. With this "debug" code you will be able to see the identifier name and the content data that is stored into it.
