   A problem with newbies/oblivious is that they tend
   to search the web for fixes to whatever minor prob
   and then just cut-n-paste. They don't/can't even
   consider what those 13 params mean.

   Do they "deserve it" ? That is one way of looking
   at it ... but too often it's the sites offering
   the canned fixes that fail to explain clearly.
