"My world is really about data structures." Also good. I tend to take the perspective of features/impact to end users, so my feedback is about that. But great project to put your data driven back-end to a real use case as a way to learn and have fun with. Another project that is bit 'on pause' that's perhaps more in your corner, is my attempt to set up a search engine for all charities, based on open data. https://github.com/juliuszelf/global-charity-search-engine https://github.com/juliuszelf/global-charity-search-engine Challenge is not even so much gathering the data, but figuring out a use case to make such a search engine valuable to a specific set of users, so it will get used, get feedback and can grow.
