The fully functional D800 AF thread - drop a line!

The flaw with that example is it's like going to an AA meeting and taking a poll on who has a drinking problem.  The results are going to be more than a little bit skewed.

Happy people typically say nothing, which dramatically exaggerates the perceived amount of disgruntled people.  This goes for any product or service, not just cameras.  An unhappy customer is FAR more likely (probably 100 to 1 or more) to take the time to complain than a happy one is to take the time to write about how satisfied they are.  That is how human nature works, in pretty well any imaginable scenario.  When people feel "wronged" they will go to the ends of the earth to make others aware, or to "correct" the situation to a degree where they feel like they got their "justice".  When people are happy, they just keep on doing what they're doing.

Like that cruise ship off Alabama that got stranded.  There were over 4,000 people on that ship - no small number of people.  Could you survey them and ask if they would go on a cruise again, and then come to the conclusion, based on the survey results, that most people do not have good cruise experiences?  A crude example, perhaps, but you see the point.
