re: Do you have any deceased family/ friends as Facebook friends?

Yep, quite a few actually.

Their parents/siblings/kids post stuff to them all the time.

One of the worst is a girl I only knew a short time before she got sick. She has a really young daughter and over the last 2 years since her mom died there'll be a really random I miss you mommy post that comes across my newsfeed. Sometimes it really takes me back, others it pisses me off because the kid is too young to type that well and I know it's the Dad finding some way to let her keep a connection to her mom, but it seems a little too public to me and it's heartbreaking to see a kid in mourning.
