  • 11. avg. del.icio.us user in sample max 217 bookmarks 9268 62 annotated bookmarks 9253 2.8 tags per bookmark 47 3/6 subscriptions 371 2/16 returning bookmarks 1026

  • 13. estimated e ects from regression 1 2 # bookmarks .84** .77** avg # tags .17** .14** uses network .23** # subscriptions .006* # returning bookmarks .19** * p < .05 ** p < .001

  • 16. thank you!
