After last week's column, Jessi Zambrano wrote about Indeed.com, a job metasearch engine not included on Mr. Knight's Top 100 list. Job search engines have been among the most successful innovators, and they've also been among the priciest search-related acquisitions. Searching for jobs is also one of the few search activities that truly matters to consumers' lives. Compare shopping search ("I want a good deal on something I plan on buying") with job search ("I want a new/better job"), health search ("I'm trying to diagnose/care for myself or a loved one"), and dating search ("I'm lonely"/"I want to start a family"). The latter three categories really matter, so expect search pioneers to emerge from them. I'd include some kind of food search in that bunch, but once you're online, searching for food is generally not a matter of fulfilling primal necessities but finding a decent takeout joint.

That Swoogle is hard to parse is in a way ironic, as the gist of the semantic Web, to oversimplify it, is to provide a way for all forms of online content to better understand themselves and each other. For instance, if a search engine or other content site were to index or link to this column through the lens of the semantic Web, it would know that this column has everything to do with search engine innovation and nothing to do with obscure forms of poetry. It would also realize that Aaron Goldman is an esteemed MediaPost columnist and not this septuagenarian who has jogged 200 miles in 72 hours, and it would surely never mistake me for the more infamous individual who shares my name. In the most utopian visions for the semantic Web, such as those shared at a DoubleClick Industry Insighters Salon earlier this month, the Web will be so adept at understanding your own interests and wants that you won't need to search for anything at all.

That's one of those beautiful ideals, to become so good that you make yourself irrelevant. Could we really get there one day with search?

It's unlikely. Even if any form of search became that good, we're still hunters and gatherers at heart. We'll always want the empowerment of thinking that searching is a skill, and if the right result is presented to us, we'll take the credit, even if a computer programmer or algorithm actually made it happen. That means that the ideal search engine of the future, the standard every engine should shoot for that truly gives consumers what they want, will be one step shy of perfection.

This commentary is insightful. I recommend it to others.
