Tailscale is a highly successful, verifiable 'unicorn' ($1.5B+ valuation) in the secure networking space, solving critical NAT traversal and VPN configuration challenges. While the project itself has immense utility, market fit, and verifiable traction (millions of installs, Series B funding), the specific submission provided is low-effort (hyperbolic claims like 'most people', lacking specific metrics). The score reflects the massive real-world scale and utility of the project, slightly penalized for the quality of the submission text.
