Facebook Goes Further Asymmetrical, You Can Tag Non-Friends in Comments

Facebook has learned quite a few lessons from Google+ and applied them already, not only when it comes to features but to the way they're announced, as more come from the engineers that work on them announcing the changes on Facebook itself.

The latest example is a subtle change to the ability to tag any user on Facebook in comments, not just friends, for those that have enabled the "Subscribe" ability.

This makes it possible to notify them about your response, further moving Facebook towards an asymmetrical friend model, like Twitter and Google+.

"Heads up to those using Subscribe on your profiles: Now you as the owner of a post can tag non-friends in the comments thread of your public posts, which will make dialogue easier. When you tag the user, they will be notified that you responded to their comment. Right now this feature is only available on profiles," Facebook announced.
