Do you leave your platter spinning while switching


I have read various articles that advise you to leave your platter turning while switching records. I have yet to find a good reason behind this suggestion. What are you guys and gals doing? What would be the benefit of leaving the platter turning vs stopping it?

I always stop my turntable spinning while changing records.  I do give the platter a helpful push to start it spinning when I start it back up. 
I've had my turntable running since the summer of 2012, hoping for a definitive answer.
With my new Origin Live Sovereign with the Gravity One record weight one of the really surprising pleasures is not having to stop the platter. So nice. Not to mention the lack of motor and belt wear from letting it run. Sweet.
