1. A computer-implemented method for enabling users of social-networking applications to interact using virtual personas, at least a portion of the method being performed by at least one physical computing device comprising at least one hardware processor, the method comprising: creating, by the physical computing device, a social-networking identity associated with a user of a social-networking application; creating, by the physical computing device and as part of the user's social-networking identity, a plurality of virtual personas that represent different real-life roles of the user, the plurality of virtual personas comprising: a first virtual persona of the user; a second virtual persona of the user; after creating the user's virtual personas, receiving a request at the physical computing device to establish a social-networking relationship between the first virtual persona and another user of the social-networking application; in response to receiving the request, directing the social-networking application by the physical computing device to establish the social-networking relationship between the first virtual persona and the other user without establishing a social-networking relationship between the second virtual persona and the other user; defining, by the physical computing device and based at least in part on input from the user of the social-networking application, a first geo-location associated with the first virtual persona and a second geo-location associated with the second virtual persona; upon defining the first and second geo-locations: enabling the user to share, under the first virtual persona, at least one content instance that identifies the user's location while the user is located at the first geo-location; preventing the user from sharing, under the second virtual persona, the content instance that identifies the user's location while the user is located at the first geo-location due at least in part to the first geo-location being associated with the first virtual persona and not being associated with the second virtual persona; associating at least one photograph previously shared via the social-networking application with the first virtual persona by: enabling the user to assume the first virtual persona within the social-networking application; after the user has assumed the first virtual persona: identifying a tag request submitted by the user to tag the user in the photograph previously shared via the social-networking application; ensuring that the user's tag in the photograph is associated with the first virtual persona and not associated with the second virtual persona due at least in part to the user having assumed the first virtual persona prior to submitting the tag request.

The method of claim 1 , wherein: the first virtual persona comprises a virtual persona that represents the user's role as a business professional; receiving a request to establish the social-networking relationship comprises receiving a request to establish a social-networking relationship between the user's virtual persona that represents the user's role as a business professional and the other user of the social-networking application; directing the social-networking application to establish the social-networking relationship comprises directing the social-networking application to establish the social-networking relationship between the user's virtual persona that represents the user's role as a business professional and the other user without establishing a social-networking relationship between the user's virtual persona that represents the user's role as a romantic-relationship seeker and the other user.
