It's true that the referrer is not sent, in either http or https by default. I see it crossing the privacy line.

It could be opt-in and could encompass way more services; however, I just doubt the opt-in traffic will yield that much right now, making the whole thing seemingly not worth it.

Instead, I will again explore unobtrusive contextual search ads, at most one per page. I had them up at some point, and they were unobtrusive, but just not relevant enough.
