Twitter photo sharing service Twitpic announced an events feature last week and now they have face tagging. This way you can add the name and Twitter username to any photo you upload through Twitpic.
To tag someone on Twitpic, click the blue link that says “Add/Edit Faces.” When you tag a photo, Twitpic asks if you want to tweet out info about the person you tagged. The tagging interface is very similar to Facebook.
Twitpic recently hit 10 million users and now they are preparing to launch several new geolocation and group features. Twitpic was founded by Noah Everett. [Mashable]
