When I signed up to host a talk show on Oregon Public Broadcasting, exploring this new tool actually added to the appeal of the job. During my time there, PIN helped us find many great sources we may never have otherwise. We turned to it more for people with first hand experience than as an “experts” database. OPB used PIN extensively for its Peabody award-winning series on the recession http://news.opb.org/hardtimes/ It did take a full time person to manage the database because of the specific  (and generally good) criteria PIN set up for the number of times network members are contacted and so forth. The biggest challenge was expanding the network to reach into communities not already in the station rolodex. Sometimes I felt like PIN enhanced a closed circle of listeners and news providers. A side note: I always thought it was funny that just hearing the name on the air you couldn't tell whether it was to gain knowledge from the public or to get them riled up.  Insight or incite?
