• and
• responsive to determining that the context indication is a significant context indication:
• identifying an organization corresponding with a profile hosted by the social network service and having a location proximate to the current location of the first member as indicated by the significant context indication;

• a stock price of the organization, number of employees for the organization, other members of the social network service employed by the organization, and news associated with the organization;
• generating notification content based, at least in part, on an analysis of the significant context indication, the profile data of the organization, the profile data of the first member, and profile data of the second member;
