This has the potential to age well (as all P2P creations do). My feedback is that more effort needs to be made on the ui/ux. Without looking at this thread, I'd have assumed it was a reddit-style board more than it is a marketplace. I also did not want to create an account, it would be much better to be able to see more of the functionality in action as a guest before being forced to setup an account, and generally I think that if guests can see more of the functionality before being require to setup an account, willingness to set one up increases. Just my 2 sats. Good luck with the project!
