Advertising 2.0
A long post speculating on how RSS impacts the future of contextual ads. 2.5 words: profile-based ads.
Your feed/micromedia reader is going to need your preference info in order to efficiently allocate your attention. You'll reveal it because efficient attention allocation is worth a great deal to you.
Of course, reaveling this info will let smart producers aggregate detailed preference info that can serve ads targeted as tightly as adware, but without the evilness.
Profile-based ads are going to be a key (edge) competence for Media 2.0 players (as I've argued many times before). Note that RSS AdSense Google style is
not profile-based - it's just the same old competence leveraged into a new domain.
