I'm targeting everyone but analyze: what audience size should I optimize for? Map the audience size psychology: trying to reach millions vs. serving thousands deeply. Calculate: would optimizing for smaller but more engaged audience drive more sustainable growth? Give me the size strategy: this audience size is my realistic target, optimize for depth not breadth. Include: when smaller audience is smarter, how to resist chasing viral at expense of community, and why trying to be for everyone makes you for no one.
