Adsense is great because it's simple to wrap your head around, regardless of your experience/skill level. I joined way back in 2003 when it first came out, and have had over 90 niche sites since then. I've flipped many of them, so that's another income stream through Adsense. It definitely changed the lives of many previously struggling online marketers.
