Investigative reporter wanted for press events

Mashable, a social media website, has a job opening for a "seasoned" investigative reporter to cover the Bay Area. The job comes with three key responsibilities, only one of which strikes me as having anything to do with investigation or reporting. See if you can guess which one:

*Sourcing original stories about the tech and social media world
*Taking regular meetings with companies in the area and going to press events
*Speaking at events and participating in press interviews

To get the job, candidates must have at least two years "at an established news organization doing investigative reporting."
