My uncle past away recently. Within a few minutes of his passing a cousin of mine (not one of his children) posted a status on Facebook that read something like "RIP Uncle, we miss you." Now the problem is my aunt, his sister, hadn't been notified of his passing. Luckily the post was taken down before she saw it and she was notified tactfully.
Later my own sister--who was closer to our uncle than I was--posted a status update that said something like "RIP Uncle! We miss you and say hi to Grandma for us!" To me this was incredibly inappropriate and I convinced her to remove the update.
My question for the slashdot community is: where is the line? At what point to people offend others in their quest for condolences online? I understand that people in grief need love from friends and family around them, but at what point is their need inappropriate or even excessive? How do you tell someone who appears to be grieving that they're taking it too far, and maybe social networking sites aren't the best place to publicize their grief?
