Dealing with Grief Via Social Networking

I was just reading a facebook thread dedicated to a friend I lost in 2007 entitled "In Loving Memory of [name withheld]" and found posts ranging from the day of the accident all the way to a few days ago just to express thoughts. Is this really appropriate? Do the deceased really check facebook from their heavenly paradise? I understand that it is a way of coping and releasing emotion for some people, but I just don't think that is the way to go about it. Things so personal are for a journal or your prayers at night--not a social networking site that likely contains everything from porn to internet predators. The thread is full of condolences for the family and funny inside jokes and it may help some who wish to keep him alive as much as possible, but I think facebook has become much too public to be expressing mourning. Just as your status doesn't need to tell me that you're waiting 7th in line at Tom Thumb with a bag of bananas, it doesn't need to tell me that you're thinking of that one time at the water-park with your childhood friend who passed 5 years ago. I hope this doesn't sound insensitive, but if I had the desire to visit those feelings, I know I would do it in the comfort of my privacy or with someone who shares the same feelings or memories. Death is such a delicate subject and it is not to be "liked", "requested", or "commented on" and its delicacy is stained with frugal social network postings.
