Not where it used to come from:

Investigations ensued. The chiefs of two redevelopment agencies were forced out. One of them faces criminal charges. Yet the main revelations came not from any of San Diego's television and radio stations or its dominant newspaper, The San Diego Union-Tribune, but from a handful of young journalists at a nonprofit Web site run out of a converted military base far from downtown's glass towers - a site that did not exist four years ago.

Local TV news fell into "if it bleeds, it leads" years ago. Local newspapers forgot what their job was, and decided that it was running ads and AP stories. Someone had to pick up the slack, and it looks like it's being done: by smaller, more nimble organizations. It doesn't take a huge budget to cover local news; it just takes motivation.
