Abstract: In one embodiment, one or more computing systems may receive an indication of a first location of a first mobile-client system of a first user associated with an online social network. The one or more computing systems may identify one or more second users from among a plurality of users associated with the online social network based on one or more notification rules. Each identified second user may be associated with a second mobile-client system having a second location within a threshold distance of the first location and may be within a threshold degree of separation of the first user on the online social network. The one or more computing systems may send a first notification to the first mobile-client system of the first user. The first notification may reference one or more of the identified second users.

The computing system may send, to a client device of the second user for display, one or more of the content items based at least in part on the calculated content scores.
