Indeed, and there are real examples of local reporters uncovering corrupt congressman based on data in these public records. This is a lot harder if they have to travel to DC and sit in a basement reading room to pore over paper ledgers.
Where 'harder' is 'more expensive' and we know that the present newspaper model doesn't look like it can support expensive endeavors. Investigative journalism in the info age is only possible if those practicing it have info age tools.
Well, yes, but "harder" as in "more difficult" too. It's basically impossible to do anything useful with data stored in a paper ledger that's only available in a basement reading room a few hours a day and copies cost $0.15 a page.
