They say hindsight is 20/20, but in the case of  Yahoo (YHOO) -- which has successfully botched one opportunity after another -- hindsight might as well be projected onto an IMAX screen.

Strike 1: Earlier this year, Yahoo turned down a merger with Microsoft (MSFT). CEO Jerry Yang felt the buyout offer of $31 per share undervalued the company.

Strike 2: Holding stubbornly firm to that sentiment, Yang declined even after Microsoft upped the offer by $5 billion, to $33 per share.

Strike 3: Months later, Yahoo lost an important advertising revenue deal with Google (GOOG), surrendering market share in the process.

(Incidentally, the current value of Yahoo's stock is hovering around $10.)

As the company enters crisis mode, Minyanville asks: What other business can Yahoo go into if this online thing doesn't work out?
