I'm not sure if it's just your most recent job title or any update that triggers that, but I did get significantly more views when I was actually looking and did trivial updates on my profile every couple of days. I wouldn't necessarily want to signal that I was looking to my current employer or coworkers though. I'm aware you can turn the "notify your network of profile changes" setting off, but I wonder if it's a wise thing to do.

And, all that twiddling of one's profile seems like a stupid thing that I'm reasonably sure people generally don't do. Maybe I just need to write a bot to automate it.

Sigh. I don't know how to LinkedIn. :P
