Normally I would ask: how do you make money? How do find gigs, jobs. But I want to respect your privacy. Being "famous" has often given me opportunities. But the potential downside is clear.
By the way I'm not arguing that anon devs should dox themselves. Everyone has to make their own cost-benefit analysis, and/or just follow their preference.
True, as soon as you want to make a living or create a "brand" privacy has major tradeoffs. It's probably more a matter of clearly and consciously separating public and private life.
