For the individual county it's probably not a ton of data, but multiply it up, it's a lot for all the counties in e.g. Philadelphia.

Normally there is data, meetings, events and so that you wouldn't report on in a newspaper, because it's really only relevant to maybe a few thousand people, but for those thousands it might be really important.

My city publishes a lot of stuff on their website, it's hard to find, relevant to maybe a thousand people, maybe less. The school board meetings, public utility companies, companies in general all publish massive amounts of information that's never surfaced, but is relevant to those living in the vicinity. Being able to collect all of this, sort it, assess it's relevans and produce hyper local news could be a massive boost for local grassroots movements and participation in local affairs and elections.

Agree that the permutation becomes a problem, but the organization should be super simple: the state mandates the use of some standard index file format for all municipalities governments, not unlike how sitemap.xml works for a website index.

There is a community-run project that standardizes each election's results across states, counties, and precincts. It could be a template for local info releases.
