Like so many others on this site...

...i'm just doing this for the points.  "and what are the points good for?" my wife will inevitably ask. 
man, i don't know.  they're points.  they're good for keeping score.  i've been collecting them in one form or another for all my life. 
the grades i got in school?  points.  the performance reviews at work? points.  and now i collect points on the internet. 
it's a brave new world, people.
