Proof of Usefulness Score
You're In Business

California Tennis (CaliTennis.com) is a functional photography portfolio providing high-quality, Creative Commons-licensed images often used by tennis blogs and Wikimedia. However, the submission itself suffers from severe quality issues, including demonstrably false claims of audience reach ('everyone', 'most people have used my product') and misused terminology ('marketcap'). While the underlying content has genuine utility for a niche audience, the project lacks technical innovation and the traction data provided is unreliable. The score reflects a working niche content site with poor submission credibility.
