Definitely!
When speaking to a mate about this idea his response was:
"If people can make millions using F...book to sell stuff, then there is no reason why you can not do it on Steemit too....."
I see a potential for more than just a "Classifieds " tab as the platform uses cryptocurrency and that just opens up boundless opportunities to all of us here.
I completely agree with that assessment. Even the other platforms are using it in some way, why not try to make our own and try to make it better. That's like I keep thinking of a Steemit gaming network where the Steemians can go to play video games or RPG-style group games (D&D style).
Sounds like a good one.
Hopefully you'll get the concept up and running and all the gamers here on Steemit shall kick in!
