Users are exposed to a number of platforms in the digital world. Each platform has it's own quirks.
The typical strategy from a creator/publisher point of view is to create a core piece of content. Modify it for different platforms and publish them strategically. There are services that allow you to do this fairly simply.
Then there are open protocols in this space like RSS which enable sharing of text based content. Podcasts also follow a standard format allowing a creator to publish to different podcast players at the same time. Spotify announced an OpenAccess platform that will allow creators to publish their paid audio content on Spotify while still maintaining their direct relationship with their audience.
The need from the user point of view is quite clear here. We have preferences between different types of content. Some might like to read a full-fledged article or watch a Youtube video on the topic, or read a condensed twitter thread or, listen to it as a podcast form. While the underlying content is the same, the delivery channel is different.
The ways in which the user can interact with the content is also different in each case. In twitter they can retweet it or comment/like a twitter thread. While a blog post can be shared with others over email or any messaging social media app they use.
Monetization is different in these platforms as well. In Youtube the primary forms of monetization is either through the built-in AdSense or having In-Video sponsors. While the monetization for a blog/podcast could be a direct subscription model with individual users.
