"I wish mainstream journalists would start doing this".
Spin it however you want, fewer and fewer mainstream journalists are able to focus on this. I work with a dozen or so newsrooms a year on FOIA, CAR, and other investigative reporting training, and in most newsrooms only 1 or 2 hands go up when I ask who has filed a public records request in the past year.
MuckRock was built to change that: To make it easier to add document-requesting and analysis to the daily news cycle, to help non-journalists get interested, excited, and able to request and share documents, and to enable large scale-FOIA projects like request BAH files from dozens of agencies.
And we've found that lots of people do care about it at the state/local level, but news organizations are a) terrible about marketing their work. b) assume readers aren't interested in the nuts and bolts. c) let that work die in obscurity, content to try to win awards with it rather than to truly engage the public.
So yes, this is a flashy dump of documents, but we've helped hundreds of others do meaningful, smaller scale stories, and whatever way you cut it, I don't think there's enough groups doing that.
I also keep my own list of interesting, public-records driven stories:

Encourage anyone who is interested to reverse engineer them and try those requests in their city, state, and country.
