Mastodon accounts can reach people outside the Fediverse by using posts with public visibility. There's a guide to post visibilities here:

Anyone can see a public post through links to the post, or posts embedded on a website. Here's how to embed a Mastodon post on a website:

Mastodon accounts can also be followed by non-members through RSS readers, just add .rss to the end of a profile's web address (for example https://mstdn.social/@feditips.rss).
RSS feed readers basically let you follow websites as if they were social media accouhts.
On RSS apps you put in a feed address (for example my Fediverse profile's feed is https://mstdn.social/@feditips.rss) and whenever a post is added to the feed it will appear in your reader.
By adding/following feeds from interesting sources, you will end up with a timeline of interesting articles. So, it's like curating your own news service.
