Use any website as a google doc, and get paid for posting notes about DEFI! Or build up onchain reputation by curating any public good information.
To abstract away complex web3 interactions, I am using Portis web3 provider. It's great for my use case because the login is pretty similar to what newcomers are used to from the web2. And it's especially nice in this app, because users can skip signing loads of confusing IPFS messages. I built a chrome addon and a demo page, using React. I use 3box to access IPFS, to save content, and to track the relationships between ETH addresses.
