One of the key reasons for using a microformat (hPage) is the principle to "design for humans first and machines second".
We provide an Inspector tool on our Demo store to meet this principle and hope that, with the microformat's community's help, we can make the data visible in many other tools.
We would like to make website publishers and users more aware of the data being declared and collected so it can be more accurate and therefore more beneficial to all involved.
Currently many users are unaware data is being collected at all.
Am I missing something? Unless consumers start demanding to know what information is collected about them, I don't think that the benefits jsHub has for ad providers are important, and that they won't implement a plugin until they're pushed by some other forces. In other words: the merit of technical innovation isn't enough for them to change their behavior, and they need a bigger incentive in order to consider using jsHub at all.
