Ahh — not being a publisher, of course I wouldn’t know that. But still, the same question remains. As you point out. How would the publications make money? Ads seem like the only option if the onus is on publications.
Honestly, it seems kind of dumb to me. Because people probably outnumber publications 100 to 1. There’s more of us and we have the weakest set of features. Let us upgrade for a nominal fee and voila. Money happens.
