Blogs that aren't about answering Oracle Obscure Platform 6.75a-R2 questions. Blogs that aren't about mesothelioma. Blogs that aren't "review" websites.
Honest, good old fashioned smart people writing thoughtful stuff.
Based on who I've talked to in areas of business and politics and the visible spread of ideas in Australian public intellectual life, the demographics for the blogs I directly host are amazing. Highly paid professionals all round. They're read in ministry offices and C-suites all over the country.
To scrape some of this high-quality audience $$ I'd need to adopt a very high touch advertising policy and use invasive user tracking to prove my demographics. I don't have time or the moral flexibility and neither do the bloggers.
Hence: how do the blogs I like make money?
(Answer right now is: at their dayjobs.)
The technology I've developed allows users to be tracked visiting participating websites without the websites being able to piggyback on my scheme to track users across multiple sites. It's resistant to the visit falsification attacks present in any standard tracking scheme.
Pointless without a business, of course. So watch this space, I suppose.
