It’s freely available, but aggregating it could definitely be of value. Most users don’t know how to query event data across the network, let alone analyze it in a meaningful way. And sure, people might not be compensated from the get-go, but the ability to do so via micropayments is incredibly easy and could act as a draw for more use of an ad market that does support direct compensation. Small businesses all won’t have the ability to do all this themselves, and oftentimes they don’t feel great about throwing out ads on whatever platform they’re using, not knowing what’s being done with all the data or who it’s even going to reach. Paying a service to do the analytics and giving businesses the ability to purchase an ad targeted to those who are most likely to buy a specific product or service by buying data directly from them reduces ad costs for the business while also increasing conversion rates. The customer is also compensated for buying a product they actually want, and a relationship is built. Market forces and sentiment would drive adoption to ad markets that most effectively benefit both parties.
