Warm up or not?

Warm up or not?
Ok in the winter I let my truck run for at least 5-10 mins before I drive it to let the engine warm up a little and in the summer I let it run until the RPM's drop down. From what I've been reading lately that's not the right thing to do, apparently I'm doing more harm than good? What's everyones take on this? Am I hurting it more by doing letting it idle a little longer? I just thought when it's between 0-30* it'd be better to let it warm up and let the oil get to where it needs to be instead of turning the key and going.

A friend of mine that would work on trucks said it is a good idea to let the truck idle for about 30 seconds before putting the truck in gear. He said it would help stuff last a hair longer because it pumps the oils and lubes before you start putting metal together under load (like shifting into gear). I don't know if that is true or not but I figure 15-30 seconds wont hurt anything, especially in comparison to sitting at a red light for a minute or two.

Here is a terse summary.
Blow-by contains water, unburned fuel and carbon. They all take a toll on your oil, but the worst may be the build up of carbon deposits in ring grooves. Those deposits will interfere with the rings ability to seal, leading to more blow-by.
