receiving authorization for the user to append media segments to the media presentation; and

wherein appending the first user-generated media segment to the media presentation comprises appending the first user-generated media segment to the media presentation based on the user being authorized to append media segments to the media presentation.

9. The method of claim 1 , further comprising:

receiving, from a second client device associated with a co-user of the one or more co-users, a second user-generated media segment;

appending the second user-generated media segment to the appended media presentation to create a twice appended media presentation; and

sending, to the client device associated with the user and the one or more client devices associated with the one or more co-users, the twice appended media presentation.

10. The method of claim 1 , wherein determining the group of co-users connected to the appended media presentation is based on social networking contacts of the user.

11. The method of claim 1 , wherein determining the group of co-users connected to the appended media presentation comprises:

identifying one or more co-users tagged in the appended media presentation; and

adding the one or more co-users tagged in the appended media presentation to the group of co-users.

12. The method of claim 1 , wherein determining the group of co-users connected to the appended media presentation comprises:

detecting a face of a potential co-user within the appended media presentation;

determining the face matches a co-user connected to the user; and

adding the co-user matching the face to the group of co-users.

13. The method of claim 1 , wherein receiving the indication from the client device to share the appended media presentation with the one or more co-users comprises receiving, from the client device, a selection of the one or more co-users from the list of recommend co-users.

14. The method of claim 1 , further comprising:

identifying one or more additional co-users connected to at least one co-user in the group of co-users; and

supplementing the group of co-users to include the one or more additional co-users.

15. The method of claim 1 , further comprising providing a graphical element within the appended media presentation that, when selected, indicates a request from the user to share the appended media presentation with co-users.

16. The method of claim 15 , wherein the graphical element is a share button overlaying the appended media presentation.

17. A non-transitory computer readable medium storing instructions thereon that, when executed by at least one processor, cause a computer system to:

maintain, for a user associated with a client device, a plurality of media presentations, the plurality of media presentations each comprising one or more user-generated media segments received from a plurality of client devices associated with co-users of a media presentation system;

receive, from the client device associated with the user, a first user-generated media segment;

analyze the first user-generated media segment to identify a content element within the first user-generated media segment;

determine the content element within the first user-generated media segment relates to a media presentation from the plurality of media presentations;

append the first user-generated media segment to the media presentation to create an appended media presentation based on determining that the content element relates to the media presentation;

determine a group of co-users connected to the appended media presentation;

provide, to the client device associated with the user, a list of recommended co-users with whom to share the appended media presentation based on the group of co-users;

receive, from the client device associated with the user, an indication to share the appended media presentation with one or more co-users from the list of recommended co-users; and

send the appended media presentation to one or more client devices associated with the one or more co-users.

18. The non-transitory computer readable medium of claim 17 , wherein sending the appended media presentation to the one or more client devices associated with the one or more co-users comprises sending the appended media presentation via a communication system.

19. The non-transitory computer readable medium of claim 17 , further comprising instructions that, when executed by the at least one processor, cause the computer system to:

receive, from a second client device associated with a co-user of the one or more co-users, a second user-generated media segment;

append the second user-generated media segment to the appended media presentation to create a twice appended media presentation; and

send, to the client device associated with the user and the one or more client devices associated with the one or more co-users, the twice appended media presentation.
