As answered by people managing Eloquent JavaScript and WaitSpin.
WaitSpin's answer:
WaitSpin introduces a new developer attention surface: the AI-agent wait state. Instead of ads in feeds or popups, it uses one opt-in sponsor line in the status surface developers already watch—without accessing code, prompts, or any developer data.
WaitSpin's answer:
Unlike traditional developer advertising channels (newsletters, banners, or social feeds), WaitSpin operates inside the developer workflow—during AI-agent wait states when attention is naturally focused. It uses a single, opt-in sponsor line instead of intrusive formats, and is built around a strict privacy boundary with no access to code, prompts, terminal output, or repository data. This makes it both more contextual and less disruptive than existing alternatives.
WaitSpin's answer:
Developers who actively use AI coding tools (IDE or CLI) and dev-tool companies looking to reach them during real workflow usage.
WaitSpin's answer:
WaitSpin's answer:
TypeScript/JavaScript, VS Code Extension API, CLI integrations, and cloud-based backend infrastructure for ad delivery and impression tracking.
