Look at this line from _minifeed.html.erb:
<%= render :partial => 'shared/minifeed_item',
:collection => current_user.feed %>
In simple terms, it says "render this collection (current_user.feed)
using this partial (shared/minifeed_item) for each item.
In Rails, partials follow the naming convention of being prefixed with
an underscore, so in this case, the parameter "shared/minifeed_item"
corresponds to the file "app/views/shared/_minifeed_item.html.erb."
You may want to review the Rails documentation for
ActionView::Partials (or nearly any documentation on Rails and views)
for more information.
