I appreciate your responses and I am taking what I find valuable from them.
It is clear for me now that you are not the audience for this kind of websites and it's totally fine. It helps me identify the right audience and the right approach to it. I am asking around and making my own research and in the end it's a matter of testing it in the most MVP way possible, to see if there's interest or not.
I cannot respond to each comment. I like discussing the opportunities, to see how the goal can be achieved, what could be adjusted to achieve it and I got some of such comments also. but not a direct statement that it won't work, because you base it on your experience and on your point view and on your life situation
but as I said, it's ok and I appreciate your responses. I just take what's valuable in them for me.
