I enoy Facebook's naive assumption of honesty

On The Facebook (have you heard of it? I think it's gonna be big someday) if you say you're attending an event, that appears in your feed: "Richard Platel is attending blah blah". Then, after the date of the event has past, sometimes this appears in your feed "Richard Platel attended blah blah blah". Facebook just assumes that you're reliable, and if you say you're going to do something, you do it.
