Abstract: User input including a social network notification symbol followed by a social network tag is detected in association with a social network user interface. The social network tag includes a text keyword that identifies a social network topic within the social network. A referential third-party social network user notification subset within the social network is defined as a subset of social network users within the social network that follow the social network topic. A referential third-party social network notification is published to the defined referential third-party social network user notification subset within the social network. The referential third-party social network notification includes the detected user input that includes the social network notification symbol followed by the social network tag.

The social network tag includes a text keyword that identifies a social network topic within the social network. A subset of social network users within the social network that follow the social network topic identified by the text keyword of the social network tag is determined. A referential third-party social network user notification subset within the social network is defined as the determined subset of social network users within the social network that follow the social network topic. A referential third-party social network notification is published to the defined referential third-party social network user notification subset within the social network.

Abstract: A computer detects an entry of content by a first user in a collaboration application and determines the entry of content contains an identification of a second user, the identification indicating the entry of content and the identification are to be visible only to the first user and the second user. Responsive to determining the entry of content contains the identification of a second user, the computer copies the entry of content. The computer then sends the copied entry of content to the second user in the collaboration application.
