San Francisco-based TwitVid.com, a site which links videos to Twitter, has rolled out a trio of new features for the service today. The site--a project of EatLime--said it now allows users to see the most popular videos being shared, real-time, on Twitter, ranking those videos based on search terms and popularity. The firm also now allows users to track views of the videos they have tweeted, and a new virtual gift feature to allow members to provide virtual gifts to others on the service.
