Hey @ackza - sorry for the late reply, I did not get a notification for whatever reason. To answer your question, no there are not any social media apps on Koinos and I don't know of anyone who's developing one (at least not publicly). I know the Koinos Group team has no interest in doing a Steemit 2.0 or any other type of social media so if that were to happen it would be some other team. Thanks for the suggestion about doing a swap.KOIN on hive-engine - as far as I know this would need to be setup by the hive-engine team (if I'm wrong feel free to point me in the right direction and I'll forward it on to the Koinos Group team and community).
