The rationale for the 50 person limit is: > Because your personal network is limited to your 50 closest friends and family, you can always trust that you can post any moment, no matter how personal. But as others have pointed out, 50 is just an arbitrary number. There might be more than 50 people someone is happy to see a photo, or there might be less. For risque photos, someone may only want a subset of their friends to see it. A better system would be to allow users to have multiple overlapping subsets of visibility, with one being the default.
