On second thoughts, I'm not very convinced at all that Google's AdSense is any sort of business model for this blog. Ads needs loads of people. Whereas self-describing Smart Disorganized Individuals are probably rare as hen's teeth.
Not only that, but after casually glancing at some of the ads so far, I don't think they're that well matched to the content yet. Maybe they'll get better. (Is AdSense adaptive?) But how many times do I need to mention "wiki" before I get a wiki related, rather than blog related ad?
Hugh Macleod has news of some ideas that might help on the modelling front.
