Mark's grinning face right above this announcement bothers me for some reason: http://cl.ly/image/2k0p2v2A1U3t
many gmail users now have icons (gee thanks, G+), and I can imagine that this awkwardness happens frequently in death notice emails sent to family and friends. Swapping it with even a generic frown face icon might do.
I emailed support at linkedin and told them of the passing - never got a response - but the alerts eventually stopped... though I do not attribute their stopping to my email to them.
