This week brought the further merging of new and traditional media when Amazon's Jeff Bezos bought the Washington Post for $250 million. The prevailing sentiment from media observers was one of hope -- hope that someone as innovative and entrepreneurial as Bezos can save this valuable part of America's cultural infrastructure. With all the talk this week about preserving great journalism, it's also a valuable opportunity to ponder what's missing from our media landscape. If the purpose of journalism is to give people a better sense of what's happening in their world, reporting only on what's broken isn't enough. How about more on what is working? At a time when our government is deeply dysfunctional, showing how people are having a positive impact in their communities -- and how others can too -- is essential. Let's just hope Bezos succeeds in reviving his new purchase before his 10,000-year clock runs out.
