Change of project structure

[zacharlie]

Project should promote community contributions rather than hinder it... without promoting spam or diluting the content quality (this is a curation after all).

This started out as some copy-paste links sorted by region, then added some meta-mojis to aid discoverability. The actual content structure atm is less of an issue since a single contributor can quite easily manage it, but a more suitable project structure might be useful, especially as the project grows. Migrating sooner rather than later would be best.

Personally, I quite like the structure of https://github.com/awesomedata/awesome-public-datasets but I'm not sure it's worth trying to muck about with slackbots and whatnot when everything can rather be pretty easily managed through github directly.

Alternatively, a dedicated static site with gh-pages and actions isn't too difficult to set up either. Interested in opinions of what people seem to think is the best approach.
