Adding meta-data to search

Fred Wilson covered an interesting search innovation by one of his portfolio companies, Indeed, in which they interpolate salaries for job postings that don't include a salary.

Fred categorizes this clever trick as adding "intelligence" to search, but it's really an example of semantic extraction combined with search. Now this is a perfect example of how aspects of the semantic web will emerge. It's shallow, but very useful, and there's no requirement for exhaustive human meta-data entry or conformity to a standard.
