Following railstutorial.org tutorial, how to make the microposts be seen by all?

I am a new learner of Ruby on Rails.
I followed through the railstutorial.org tutorial and I'm trying to
learn off the sample demo app where you can to make microposts and only
the people who are "following" you can see them.
If I wanted to make it so every user can see microposts as an additional
functionality, what are the steps to do that?

Have you worked right through the tutorial? I mean actually worked
through it doing the examples.

Which bits of the new functionality do you not know how to do?

I am also a new user and I had the same question. The way I did it was to
modify the file app/views/shared/_feed.html.erb

   changing
                <%= render partial: 'shared/feed_item', collection:
@feed_items %>

   to
                <%= render partial: 'shared/feed_item', collection:
Micropost.all %>

I assumed that the OP wanted this feature in addition to the existing
capabilities rather than instead of. If however that is what he wants
then it would be better to change the definition of @feed_items in the
controller rather than changing it in the view.
