I'd make a content addressable system to have better caching, balancing, backups and history of changes. I'd like the internet to preserve its knowledge into the future. As for security, I'd enhance the web browsers to do internet hygiene - removing unwanted bits and blocking information leaks. The browser should protect user accounts from being linked together. Another major issue is payments which today is a high friction backwards process and acts like a gatekeeper. We need an equitable solution for micro-payments without too large processing costs. The last one is search - users can't customize the algorithmic feeds it generates and startups can't deep crawl to support inventing new applications. Search engine operators are guarding their ranking criteria and APIs too jealously while limiting our options. So in short, ipfs/bittorrent like storage, nanny browser, easy payments and open search.
