Facebook "Last Seen" Tag

When was the last time you logged into Facebook? Besides logging in today to grab this screenshot, I can't remember the last time I logged in. I bet there are a lot of people like me who just kind of forgot about it.

What if... NOT logging into Facebook could be a badge of honor for your profile? Imagine going into Facebook profiles and seeing users' last login times. You could measure whether someone is still active on the social network or not... and that's about all you could do.

Hardly an idea that gets anything useful done other than maybe pushing people to log in less, which is counterproductive to the overall goal of the business.

But I invite you to imagine.
