It's about time but Flickr has now added a "people in pictures" feature – it's on the right by the sets. You can type in a Flickr contact and add them that way, just type in a name and add them that way or you can use an email address.
The email address is the interesting bit – I've a few ways of getting your email address; I may have it from Facebook, I may have it from a random chat or a business card.
Previously I might have never guessed your Flickr username and that would have suited you as you might have used your Flickr account for personal pictures only; friends and family sort of stuff. Flickr's "people in pictures" option rumbles you now. If I have your email address and you've used it to register on Flickr then I can find you.
There's an easy solution; make sure your photostreams are locked and private if you'd prefer them to be locked and private.
