LinkedIn

I use LinkedIn frequently for work. I've passed 1,000 connections, which I realize is quite a bit more than the norm. However, at this point, there are at least two dead people I'm connected to. It's a little bit odd seeing them when browsing through contacts, and it's gotten me wondering --

Do folks view this as a bit of memorializing, or more likely, their families are unaware of the account and/or how to remove it?

>> Apparently, LinkedIn does have some sort of a process for removing people.
Good post on a similar topic with Facebook.
