I quit LinkedIn a couple of days ago. I got a status update of some contact or other, and thought: "What is this? Why do I have this?"

I feel much better not having something that felt so obligatory, yet so unlike me.

These networks seem to leverage social pressure as much as they solve problems.

I quit linkedin when, while trying to send a single person an invite, it sent one to my entire gmail address book. Since I didn't recall ever giving it my address book, and it was a seemingly almost purposely bad UI design that ended up with me spamming my friends and family, I promptly quit, in the middle of a job search nonetheless. There's just something about these worlds that seems unreal, or a slight version of dishonest.

Never have joined facebook and time has made me happier with that decision every single day.

I quit FB, but would never quit LinkedIn. It's key to my day to day business relationships.

I'm in research. PubMed is my LinkedIn. :)
