Facebook has just introduced the latest feature in its ongoing evolution to blur the lines between social networking and search engine- tags. The new '@' tags allow users to tag other users in posts and integrates a whole new realm of search capabilities.
The new tagging is in posts or status updates, though, rather than images. For example, if I write a post about going to my best friend's wedding, I can tag the post with my best friend's name. The tag will make it easy for other users who read my post to be able to link to and view all other status posts related to my friend no matter who wrote the posts. Its sort of like an instant search function with the tagged friend being the search term. more
