Abstract: A feed privacy module receives an indication of the occurrence of an activity in a content sharing platform and creates a private feed item of a first feed item type corresponding to the occurrence of the activity. The feed privacy module requests input pertaining to a privacy setting selection for feed items of the first feed item type and receives the privacy setting selection. If the input pertaining to the privacy setting selection indicates a public setting for feed items of the first feed item type, the feed privacy module converts the private feed item to a public feed item.
