It's another morning where Facebook, Groupon, and Zynga are getting slammed.
LinkedIn, alone among the social-media newcomers, is up!
Why is that? Well, volume in Facebook shares has doubled as its post-IPO lockups have started to expire. Groupon and Zynga have their own problems.
You could also point to LinkedIn's track record of steady growth. While its growth rate is decelerating as the law of big numbers kicks in, it's still really high, especially compared to Facebook.
