I think “siloing” and “theming” may be popular, but the AI of the search engines is quickly falling behind the actual human intelligence of the search engines.

I think Google and Yahoo will move away from AI, as they’ve found better ways to score human intelligence and relate it to proper categories. The ad mix they’ve been relying on has been bumped pretty aggressively by the way behavioral targeting has evolved in the past six months, and I expect that Google will especially move in this direction as the ad networks are aggressively targeting Google’s source of income.

Cheers.
