Forum owners, how do you "fight" Facebook groups?

@Turned my Discourse into a successful ecommerce platform!

I would just like to send a big thanks to the entire team and the community for providing such a great piece of software. It’s reliable, fast, and it blows traditional forum software out of the water! I’ve turned our Discourse instance into a small marketplace community that is slowly climbing in sales/users/traffic. The possibilities are endless when you throw a couple of plugins at Discourse. I recommend it 100%!

this is the ticket. niche niche niche.
