I had a problem where a few real friends wished me HB on or around the correct date. Another example of friends revealing your information. ;-) Seriously, though, there is a problem with friends not understanding the medium and privacy concerns. If someone does not display their birth date, it may be a clue they don't want it communicated in that medium.
