Dying to know where your friends are at all times? Want everyone to know where you are without having to take the time to "check-in?"

Now you can! (Can you sense the sarcasm here?)

Facebook is rolling out its optional Nearby Friends feature today on iPhone and Android.

It works like this: A friend will get notifications that you are nearby, but only if both of you opt-in to this feature. So in theory, if you’re out cruising around and feel some hunger pains, you can figure out who is close by and ask them to grab a bite to eat.

Of course, this can also have the opposite effect ("Oh hey, ex-lover"), which is why you have the ability to control who sees you. So if you don’t want your talkative Aunt Sally or your creepy ex-boyfriend coming to find you, don’t share this information with either of them. Of course, you can also just turn the feature off completely.

Facebook also recently rolled out the ability to ask for recommendations on music, books and more on your friend’s profile.

Which just goes to show you -- while there are some things Facebook shouldn’t do, these days there’s almost nothing it won’t do.
