This opens up my mind to a lot of possibilities.  Some poignant conversation starters for your local lunch group:<p>- What kind of investment returns did the stock of those bankrupted yellow pages make and at what cycles?<p>- What does it really take to kill an old technology?<p>- Is there a way to compete with established dying tech companies at their own game, or is it purely by trying to advance their users to your new tech?<p>- What does this say about transitional companies that possibly offer both the old AND the new techs, like the yellow pages that offer online versions?  Are they going to move forward or are they just delaying their deaths a bit?<p>- What kind of talent is needed to sustain these kinds of businesses?  It&#x27;s going to look very different from the talent that grows new business, but I can&#x27;t deny that they&#x27;re both forms of talent.<p>Lots of food for thought.
