These days I try to assume I probably don't understand! For the start of this product, we had a Design Sprint where we came up with the idea, and then brought in real Instagram users to test the idea on (with very lowfi prototypes) befor actually building!
We could learn so much more in life and have such better interactions if this were the default condition going into the unknown.
“Maybe there’s something here to be learned”
Through that lens: is the number of businesses/people that need a website builder greater than the number of them with access to a desktop computer? For the US, I'd say no. But in Asia I can see this being the case.
