Well, when Microsoft offered $33 per share, Yahoo said they were worth $40+ per share.
At the time Yahoo were trading at $20 a share - now they are at $12.
So Yahoo is losing value fast.
To be honest, Jerry Yang seems to have put a lot of faith into the Yahoo-Google tie-up, but Google pulled-out due to regulator concern.
I think Yahoo's approach to business management is still too much based on getting things done - they should seriously consider hiring a big shot CEO from another big visionary tech company which understands the web.
The number of web properties that Yahoo has is amazing - but it is very unco-ordinated, and the failure to roll out Yahoo Publisher Network ads globally - and leave it like that for the past few years - gives the impression of a company that gives up before it finishes a project.
I'm sure I could do a much better job of managing Yahoo that the current management.
