So, this is a social network, right? With the right marketing for the target audience, I think it has the potential to go far because it's a platform focused on content consumers, not content creators, and that's the most significant portion of social media users.
Very nice UI. However, I've used this type of tool in the past and always forget to use it. When I want to save something from the socials and save them directly to the apps I'm using. The experience of navigating out of the platform breaks the magic.
