I have similar feelings as the author. I aim to be as public as possible while maintaining personal privacy. I *want* to meet other like-minded people that enjoy the same topics I do.

I treat any of my public facing information as a honeypot for nerds (i.e like-minded people). In real life, if I meet interesting people, I point them to my website. If they reach out with questions, I know I found "one of my people".

On a similar note, if I an idea, project or thought of mine could benefit someone else and allow them to learn and gain from it. I'd like to publish it with my privacy in mind.
