LinkedIn likes it, Mikey doesn’t

What’s going on with LinkedIn these days?
Can someone tell me what value it brings to the site by allowing people to like and comment on alerts that your connections have updated their profiles?
Are there seriously people out there with enough free time on their hands that after they’re done trolling through Facebook they go over to LinkedIn and say, “Ooooh look! Jimmy updated his Experience to include ‘wasting work hours watching the World Cup.’ I LIKE that! I’m going to click the LIKE link. Big ups, Jimmy! You da man!”
You’re not even seeing the actual Profile update on this screen either. So how are you going to react to something you need to drill down into to understand?

I’m all about the cross-pollination of ideas between different industries and trades, but some things just aren’t appropriate.
