Question about country/city-based GeoJSON datasets

[charliejmoore]

Would it be useful to add a list of country (and some major cities) GeoJSON datasets to the data section here?

I collected a list of tons of repos that are like "GeoJSON of Germany" or "GeoJSON of Australian states" etc and I'd be happy to add them here in a PR -- would that be useful? Since there aren't currently links of this sort/level of specificity in the data section, I figured maybe they were excluded on purpose but wasn't sure.
