We're all pretty familiar with tagging people on sites like Facebook and Flickr. It's a great way to let the people who are in the pictures know you've uploaded shots of them, and it's also a good way for others to see who the persons are in the photos they're looking at.
But what if you'd rather steer clear of the walled gardens of the Web and upload photos to your own website or blog? Wouldn't it be useful to be able to tag those, too?
Enter Stipple, a recently launched startup that lets you tag images across the entire Web (see example on BritneySpears.com). The company is today launching People Dots, a feature that allows users to build a bridge between Stipple and their Twitter and/or Facebook accounts.
