It seems you are just randomly comparing tech companies by bid/sale value...what about actual value? There is incredible value to LinkedIn, and the 7x multiple is entirely sensible. They have the world's largest resume database, active users, major network effects, and near zero competition. Yahoo has nothing close to that. I'm not saying that drives a 4B$ valuation exactly, but comparing Yahoo to LinkedIn is apples to oranges.
