The top 1M website homepages were downloaded and analyzed to determine the % that use Facebook, Google+, and Twitter sharing buttons. The raw html is cached and easily searchable so let me know if there are other interesting analyses that can be done.

How many sites have a like or share button, but don't automatically run javascript to report each visit?
