AdSense or Affiliate Commisions?

I've been reading some information lately on both affiliate marketing and AdSense publishing. I guess sooner or later I need to decide which one I really want to concentrate my efforts on, since they are really two completely different and separate things.

I suppose you can certainly create websites that promote your affiliate links and also have Google AdSense ads displayed, but it seems like it's probably better to concentrate fully on one of the other. At least in the early going, since they really are two different things.

I love the idea of Google AdSense publishing because so much of what you have to worry about with affiliate marketing doesn't even apply. For instance, you don't have to worry about link cloaking, since you're not using links anyway. All you need to do is create a website, or blog, that has enough information on a given subject to attract people, bring in some well targeted traffic, and then let the Google AdSense ads do their job.

Eventually I plan to incorporate both affiliate links AND AdSense ads on my site(s), but for now I'm going to concentrate more on using AdSense, since I've already had SOME success with it.
