https://github.com/ekzhang/rustpad Cooperative online text / document editor. Looked interesting until I saw that it requires #Node.JS.

I'm also still a little leery of letting WASM run in my browsers. Not that people can read obfuscated minified #JavaScript, but if you could obtain the pre-minified source, you might be able to tell what it was doing. With WASM, you're totally just letting unauditable and untrusted code run in your browser.

(I know this has a "Get off my lawn" flavor, but that's not what is happening here. Just wait until a GRU-sponsored malware gang starts inserting malicious WASM into popular sites around the Web.)
