Zendesk Guide is a text based content item platform currently.

YouTube is a video based content item platform.

Pinterest is a picture based content item platform.

Document Libraries are document based content item platforms.

What if Zendesk Guide would be a multimedia based content item platform??
It would then not matter in what format the content would be, you would find it in the search (like Google) and would see all content Items (currently named Articles) next/under each other when clicking through categories and sections. It wouldn't matter if the content would be a video, audio, picture, PDF or HTML Text, they all would reside next to each other, not like currently an attachment/embedment within an Article.
With social media etc. our lives are so much more graphically setup and our customers are used to have content shown graphically, that just text-based driven content is not enough any more.
