It would be nice to be notified when a LinkedIn connection decided to dis-connect.
Presently when I notice the number of connections change, I scan through my address book in LI to see who is on Linked in and not a connection. Tedious.
AFAIK there isn't a (native) solution to get notified when someone disconnects from you on LinkedIn.
However, I would also think it's inappropriate. It's like saying:
Furthermore, what use does it have, if that person actively decided no longer to be in touch with you, it's unlikely you can change his mind (or not worth trying)
I've had the same question and couldn't find an answer. I would believe it is possible to track that programmatically (through an app) - though it's not done natively in LinkedIn, of course where everything is about connection, not disconnection. I haven't found an external app yet that does such a check, but if someone has, please share that with us.
I don't see a particular problem with tracking disconnections as Ivo did, because it's technically possible and it's already done in other social networks such as Twitter (through twunfollow.com) and Facebook. Liz Ryan offered three good reasons to snip a LinkedIn connection. So why shouldn't I get to know if someone doesn't want to be my contact anymore?
In addition, I don't see LinkedIn these days so much as a purely business social network anymore (it actually bewilders me that LinkedIn sees itself this way). Lots of my LinkedIn contacts are friends, who I keep in touch with because this is the network we share (plus, I don't like Facebook).
So, in short, at this stage there doesn't appear to be any automatic way to track LinkedIn disconnections. If I get around to develop one, or find one, I'll post it here.
