Almost of the above stuff is easy. Most of it is just avoiding stuff that’s stupid, but that lots of publications do. (And that make their jobs harder, for no gain.)
The challenge belongs in one place: the quality of the writing. And that’s it.
If the articles were poorly-written or not interesting or both, the site would fail.
But I believe, though I can’t back it up with numbers, that such a site with good, interesting articles would succeed very well.
[Noting for myself. Good stuff.]
