Facebook's ARPU is $58.77 in the US/Canada so $5/month. According to them, Apollo's Pro clients would earn reddit $2.50/month. Is the right number $1? I imagine that would still kill Apollo.
It seems like the problem more generally is that third-party clients cannot extract the same value from users that first-party clients can.
Has anyone tried to solve this differently? What if Reddit gave you a libAds to add in your application where you build and control the other 90% of the interface and do a profit sharing system with them.
