>>Can you host your own web search? (Or can you function without a web search?) Yes [1] [1]https://yacy.net/ https://yacy.net/ >>Can you host your own auction platform for everything? Seems odd to call this out, you must you ebay alot. I dont think I have every bought anything from ebay, i always found the "auction" format off putting, I prefer normal eCommerce. And there are PLENTY of self hosting eCommerce platforms, I am sure a few of them have a action function >>News aggregator? Yes, plent of those exist, I never use google for news, though I do not self host my own either but I could. Today I use Feedly alot, but I have run RSS readers, and other news aggregators in the past >>Global GIS with updates? Self Hosting does not mean you cut yourself off from the world of data, OpenStreetMap and other such service crowdsource data that you can then ingest into your selfhosted service. So yes I believe you can do this
