To this end, they’ve launched a “People in Photos” feature which allows members to link people in photos to their Flickr accounts, in a similar way to how Facebook does it except that I suspect there are fewer people with Flickr than Facebook accounts.
On top of this, there are a range of security options (which the likes of Facebook could learn something from) whereby users have more control over how their image is featured in a photo.
Yes, in Facebook you can remove a tag of yourself if you want, but it’s hard to remove a non-tagged association (where you are mentioned but not tagged).
The new Flickr service will send a confirmation email to non-members if they are tagged in photos to seek their approval.
How popular the service will be remains to be seen. Facebook probably still leads the way when it comes to photo tagging, and by nature tends to feature a much higher proportion of known people shots.
