1. Nope! HN is for everyone. Leap has its own unique UI and culture.
2. We haven't discussed a view only public mode in any depth. The idea of eventually allowing men to join has come up on Leap. No idea if that will happen though.
3. I don't survey users about that so I can't say with any accuracy. I also expect it depends on the person.
1) If someone put you on the spot and asked you to pigeonhole Leap, would you say it's intended to be a Hacker News for women?
2) Has there been any discussion of a observer/lurker status for men?
3) Do participants primarily shift their time spent on other (open?) tech/social forums towards Leap, or do they increase their total amount of time spent on forums to make space for it?
