The speculation and exuberance.

This rumor is over a year old; it was also first floated around Q1 last year and YHOO's stock price surged that time too. I seriously thought Yahoo was going to sell that time but they didn't. Perhaps this time is different?

Before it was a rumor. This time there's an actual official looking document outlining the offer on MS's website. I think that qualifies as "different."
