Be careful what you read on the internet. I recommend that everybody interested in good BBQing join
The Smoke Ring forum. Lots of good helpful people there (kinda like here) who love to talk about BBQ and help others.
Some people like the guy who wrote that article above don't know their *** from a hole in the wall and then write an internet article and are somehow BBQ experts?!?! He lives in California but his neighbor used to be from Kansas and showed him how to BBQ?!? He says BBQing involves cooking meat directly over the fire at temperatures of 400 degrees. Stick a $50 brisket on a grill at 400 degrees and you'll have burnt shoe leather before it reaches anything worth eating. Low and slow is the answer to great BBQ. If you don't have time to wait, you don't deserve it!
