Speaking as someone who contributed a few scrapers to the inspectors general project (https://github.com/unitedstates/inspectors-general), I think this is a great and worthwhile effort. It's actually not that hard to contribute a scraper if you know a little Python (and maybe a way to learn a little Python if you don't).

One thing that my friend who works in Open Data has told me is that it's important for websites like this to exist, to be able to point non-technical people at them and say "SEE. THIS is why you can't just publish everything as a PDF".
