People seem to like #apps that do one thing well. #TikTok works because you open the app to get a bunch of videos. You have crossed a threshold into watching videos.
The opposite is true of videos on #Facebook. People don't go to Facebook for videos. They expect text. If you open #TikTok you likely have headphones (or a speaker) ready. Needing to play audio is often an annoyance when you expect to be reading or looking at photos.
#Podcasts might be the most successful use of #RSS because it is a specialized use. You open the app to listen to something. I think most people who use RSS still have specialized podcast apps rather than just one #RSSApp for everything.
So I think generalized RSS-apps have a problem because it ends up mixing a lot of different types of #Media into one app. This might also be a problem for the #Fediverse. I know that when I am on #Mastodon I don't really click on the videos people share on here.
Do we need a special RSS-app for every type of media? Maybe not. Maybe we can use tabs and folders instead.
Instead of crossing a threshold into videoland by opening a special app you could have a tab in your RSS-app that is dedicated to videos. You have a tab dedicated to shorter texts and a tab dedicated to longer articles. One tab might be dedicated to media which needs to opened in a different app.
Of course many apps already have folders but those are usually based on dividing sources, often manually, into categories. I am thinking more in the lines of an app that does the sorting by automatically sorting each item from feeds according to type.
I think such sorting might also be good for the Fediverse. I'd be more likely to watch videos people share if they were in a different tab than the rest. So when I was in the mood for watching videos I could just open the relevant tab in #Tusky to go through the stuff people have been sharing.
