I want to write more stuff that's exposed to the public web. Almost all of the code I write is designed to run on someone else's computer. I want to build things with broadly unrestricted public APIs that let people mutate the same shared state, rate limits be damned.
The most fun I've had has been working on projects like @veloren, watering holes in which people with eclectic interests have come together to poke and experience a public MacGuffin, a commons with all sorts of opportunities for low-level chaos and mischief.
