After years of resistance toward joining yet-another-networking-site, I broke down and signed up for LinkedIn today.
I was checking out my site's analytics and saw that my first name continued to be the top keyword that was getting people to my site. I did a Google search for my full name to see how the results were. The first one was for my blog so that's cool. I scrolled down and saw a LinkedIn profile for Thu Tu, and it wasn't me!
That's when I decided to sign up for LinkedIn and establish a profile for myself. I even got a custom url with my name, which surprisingly hadn't been taken yet: http://www.linkedin.com/in/ThuTu
Update: One week later, my LinkedIn profile is showing up in a search for my name. Go me!

I know how you feel. I am still refusing to join yet another network.. For now.
