What "belongs" on the front page of HN is whatever ends up on the front page without being moderated or flagged. At the end of the day, HN is a community and it decides for itself what it wants to see and share with its members! Like the guidelines for submissions say, anything that is intellectually stimulating or interesting to hackers is fair game! Vox populi vox dei :P
I guess Susie stepping down the corporate ladder of a shitty company must be more stimulating.
Also, why the downvotes? I didn't know it was illegal to discuss how banal and uninteresting a post is. Clearly posharma and I see it that way. Yet every time this happens, people get downvoted. Why? Can't you just scroll through and move on, or do other people's opinions bother you?
