New Facebook Features: @Mentions, Browse Friends by City

facebooklogoFacebook is rolling out “@ mentions” similar to those found in Twitter. According to the Facebook blog:

Now, when you are writing a status update and want to add a friend’s name to something you are posting, just include the “@” symbol beforehand. As you type the name of what you would like to reference, a drop-down menu will appear that allows you to choose from your list of friends and other connections, including groups, events, applications and Pages. Soon, you’ll be able to tag friends from applications as well. The “@” symbol will not be displayed in the published status update or post after you’ve added your tags.

This feature isn’t working for me yet, so I haven’t been able to try it. It’s unclear how this will affect services like that allow simultaneous posting to Twitter and Facebook, especially if one has different usernames on the two sites.

You’ll be given an option to browse by City; a dropdown menu will appear showing the cities in which you have friends. Who knew that I had a friend in Pawtucket, RI?
Will you find these features useful?
