Any sites like IH but for shopify businesses?

Something like https://www.starterstory.com by @patwalls

For something that niche, subreddits are your friend ;)

Shopify organizes a few online groups for Shopify storefront owners to be able to get feedback and share their experience selling on Shopify.

Their Facebook Group (Grow & Sell) has roughly 15,000 members. Usually there are a few posts a week with activity in the comments.

There's also a slack community someone (not affiliated with Shopify) set up for Shopify owners, but it hasn't been very active and does not appear to have grown much after it's first few weeks of being active.

Having observed the FB group for a few years I think there could definitely be space for a community driven knowledge base for getting the most out of what Shopify has to offer. A lot of them have the same questions and problems around their shop. Mostly "Launched shop, getting X visitors a month, but few sales."
