YHOO and Yang deserve that their stock tanks Monday morning. Consensus seems to be $24 which would be surprise to me; Yang has proven that he is incapable of seeing the sign of the times, that YHOO is not well equipped for the future, and that MSFT would have been a good partner (not perfect, but good).
I'll laugh all Monday checking YHOO's stock.
(From a Webmaster point of view, though, it's sad. Now the chance for a convincing alternative to GOOG is gone. Sad.)
