The purpose of the content discovery module is to bring trending, relevant and fresh content to your fingertips. This results in higher engagement statistics as everybody wants to be up to date about the latest news in their specific industry.
One of the great content hubs is medium.com. Medium is like Twitter for long-form content except it has an algorithmic timeline that tells you what stories you're going to be interested in. Medium is a powerful blogging and content syndication platform and a great source for top trending content. ContentStudio has now added medium.com and its publications to its sources for retrieving fresh content.
This gives you access to countless more articles which subsequently you can categorize into your favorite topics.
