Yahoo! to buy MySpace?

Rumors are saying that Yahoo! wants to buy MySpace from News Corp, in exchange for a 25% stake of itself. I'm quite curious on how will this reflect on Yahoo! stocks today, since I imagine that most investors that aren't that well into technology will think that the over-hyped MySpace is a good target, even if those who are more insighted on the social networking world see that the deal would be really bad for Yahoo!, specially because of the late boom of Facebook, that some people already predict that will overcome MySpace.

BTW, Yahoo!'s market capitalization was $37 billion at close yesterday, meaning a quarter stake in the firm would be around $12.3 billion.
