hey @midlet,
your idea of building new app/service similar to makersplace on Hive Blockchain is a great new use case for our world. Pages like Superrare or Makersplace are very exciting new ways of interaction and opportunity of different life for many underrated, unknown artists, open hearts and crazy heads.
Higher attention on social media and higher volume on exchanges guaranteed!
Perhaps it is wise to mention this idea on official hive discord, where you can reach more devs or people with similar attitude.
I wish you all the best !
