I think you’re missing the point actually. The point is not to provide high value, the point is to drive traffic to their main product by giving -something- for free.
A few similarly sparse sites for illustrations have done well on product hunt and now it’s more common. Someone recently created an aggregator because a bigger library is definitely needed
I do wonder when I visit that site... is it just 10 free illustrations?
Nothing wrong with that, I just wonder when I visit if I'm missing anything.
