What's the benefit to just a regular old upload of a picture or something like that?
The idea is that you can create media apps, more in the direction of Instagram or Tok Tok. These kind20 images will end up in your profile gallery for example (for photography, art, whatever content people like to show on their profile), while regular uploads are more casual in the normal feed.
Oh right, yeah, well that makes sense because that Instagram format is hugely popular.
