Sorry, I shouldn't have phrased that as a direct question. I meant it in a more rhetorical sense.
Oh, sure. It's a very tough field, and would be even if the incumbents didn't have billions to throw at the problem. I definitely don't believe that the better product wins; I only need Microsoft as a counter-example.
But it does strike me as a zone of opportunity. Maybe Substack is a good partial example here. Before the web, we had magazines. Then we basically had magazines on the web, preserving much of the old structure in the new medium. With lots of flailing as people tried to find sustainable business models.
And then Substack came along with an extremely bare-bones implementation mostly using 1980s technology and a lot of writers and readers are very happy with it.
So it's more that I'm asking myself. What are the products that cost 1/100th as much that might be as satisfying for my Facebook-ish needs?
