First $200 in 10 days from a 3-part Rust CLI guide
A developer creator published a free introduction, then gated parts 2 and 3 behind a paid subscription at $10/mo. By the time part 2 was live, they had 20 paying subscribers — $200/mo from their first series.
“I published a 3-part guide on building a Rust CLI and had paying subscribers before part 2 was live.”
