Karlie here from the Shopify Support Team! I understand you're looking for feedback regarding creating a community for your online store - I just wanted to chime in here to let you know that there are some apps in the Shopify App Store that would provide you with your own forums community on your storefront.
If you're interested, you can check them all out here. I would recommend specifically checking out the apps; Xenforum, Muut, and Chatigy Forums.
I hope this suggestion helps, but if you have any questions - feel free to ask!
