"The Library of Congress has finished a report (full report and shorter summary in pdf) summing up what they’ve learned after the first nine months of their experimentation with Flickr. Here is an excerpt from the summary. Look at these numbers.
The following statistics attest to the popularity and impact of the pilot. As of October 23, 2008, there have been:
Between January and May 2008, the Library saw an increase in hits at its own Web site. For Bain images placed on Flickr, views/downloads rose approximately 60% for the period January-May 2008, compared to the same time period in 2007. Views/downloads of FSA/OWI image files placed on Flickr rose approximately 13%. Average monthly visits to all PPOC Web pages rose 20% over the five-month period of January-May 2008, compared to the same period in 2007. For additional information, see the Outcomes section in the full report.
- 10.4 million views of the photos on Flickr.
- 79% of the 4,615 photos have been made a “favorite” (i.e., are incorporated into personal Flickr collections).
- More than 15,000 Flickr members have chosen to make the Library of Congress a “contact,” creating a photostream of Library images on their own accounts.
- 7,166 comments were left on 2,873 photos by 2,562 unique Flickr accounts.
- 67,176 tags were added by 2,518 unique Flickr accounts.
- 4,548 of the 4,615 photos have at least one community-provided tag.
- Less than 25 instances of user-generated content were removed as inappropriate.
- More than 500 Prints and Photographs Online Catalog (PPOC) records have been enhanced with new information provided by the Flickr Community.
Not only is that data good news about the project but being able to say “Hey when the Library of Congress opened up their photos to commenting and tagging, they only had to remove 25 inappropriate tags/comments out of 75K instances of user-generated content” thats a big deal."
