AddThis released an interesting infographic with some statistics about users sharing habits. Among the impressive numbers: 44% of shares occur through Facebook, up 33% from last year (due both to the platform’s record growth and the release of the ‘Like’ button.)
Shares over Gmail increased by 395%, outpacing StumbleUpon, Facebook and Twitter. Shares via MySpace and Friendster dropped 20% and 31% respectively. While the data gathered from AddThis widget are by no means comprehensive, the percentages should be relatively accurate given the sample size and the number of sharing services supported.
