2. Peer Production and Remixing
Benkler (2006); Raymond (1999); Lessig (2008); von Hippel (2005); Giles (2005);
Wilkinson and Huberman (2007); Kittur and Kraut (2008), etc.

3. Remixing
The reworking and recombination of existing creative artifacts.
Most commonly in reference to music, video, and interactive media.
Widespread, and an important new communication modality (e.g.,
Manovich 2005; Lessig 2009)
Especially among use youth (Jenkins 2006; Palfrey and Gasser 2008)

4. Criticism of Peer Production
Others have suggested that peer production
and remixing are amateurish and poor quality
(e.g., Lanier, 2010; Keen, 2007).

5. “Could Hamlet have been written by a committee,
or the Mona Lisa painted by a club? Could the
New Testament have been composed as a
conference report? Creative ideas do not spring
from groups. They spring from individuals. The
divine spark leaps from the finger of God to the
finger of Adam.”
– A. Whitney Griswold (1957)

19. Data and Measures
1,271,085 projects shared before April 1, 2011.
Outcome:
Loveits
Independent Variables:
Collaborativeness (Is project a remix?).
Control blocks (similar to lines of code)
Media elements including image and sound files.

20. Data and Measures
1,271,085 projects shared before April 1, 2011.
Outcome:
Loveits
Independent Variables:
Collaborativeness (Is project a remix?).
Control blocks (similar to lines of code)
Media elements including image and sound files.
Additional controls:
Number of views
Creator tenure, gender and age

21. Methods
Negative binomial regression model on a count of loveits.
loveits = β + β log blocks + β log media + βisremix +
β log blocks × isremix + β log media × isremix +
βage + βjoined + βfemale + β log prevloveits + β log views

28. Example: Media Intense Project
Original Remix
Remix received less loveits than antecedent.

33. Takeaways and Final Thoughts
Remixes are rated lower than de novo projects by
Scratch users.

34. Takeaways and Final Thoughts
Remixes are rated lower than de novo projects by
Scratch users.
More code = smaller gap
More media = wider gap
