What is there to discuss?
DLC is a low risk exercise in guaranteed money making. That's all there is to it.
It has nothing to do with whether the content could have fitted on the disc or not. DLC is rarely more than a few hundred MB. Most Xbox 360 games have a couple of GB spare on the DVD anyway.
I disagree with you though that there is a lot of discussion on DLC, hardly true. In the sense of classical DLC - as in game addon. Not a DLC self contained game. That is another matter entirely and companies shouldn't be givin the middle finger for that since it generally speaking is entirely new content that can stand on it's own in the marketplace.
Still...Hardly a topic for discussion? Think I've basically covered anything that could possibly be discussed? It's not about if YOU like it, simply it's a way to make money easily and that's why it's getting more and more popular.
