Your analogy comparing Walmart to Yahoo is weak:
1. Walmart hasn’t make any acquisitions that are out of line with there fundamental business which they later shut down.
2. People go to Walmart and Target to buy similar things, relevance doesn’t factor into the discussion.
3. I doubt many people here know who the CEO of Walmart is, whereas we are inundated with news about Marissa Mayer in Tech and Non-Tech news.
Pehaps I have to use smaller words xrange.
