After my initial Instagram previewing, I also asked friends if they'd help me out by beta testing the website and providing feedback.
I followed up with them directly, sent them the details and waited. A couple days later I pushed them again as a reminder and made myself available for them in whatever way suited them.
I received Instagram chats, voice notes, and WhatsApps giving me vital feedback about what people liked, and what they didn't like.
With this I was able to iterate and tweak the website focusing on the pain points people were having.
Don't assume, test!
