@dansup Indeed. I think you have to be mindful of the culture of different types of apps. If I browse just images on Mastodon I'm going to get a lot of screenshots, graphs and other stuff that nobody going to a photo sharing app is really interested in seeing. Same thing happens with videos.
The key is to let the different apps have their own body of content and use federation to supplement that with the accounts that specifically want to take part in that kind of community from Mastodon etc.
