TweetPhoto/Plixi — 70 to 75 percent of traffic is from twitter

Twitter still provides about 70 to 75 percent of the traffic to the Plixi system, Callahan said, but the company is seeing more users authenticating with Facebook???s open platform protocol and pushing their photos to their Facebook wall. The giant social network makes up about 15 percent of user activity for Plixi, said Callahan, with the rest coming via MySpace, Foursquare and LinkedIn.
