Adsense has always been an interesting field to talk about.

I know many people live very comfortable life from Adsense alone but I think that field is flooded now. To start a decent website, you'll have to get a good domain and a good niche, without much competition, depending on what you website is about but the point is that most of those good domains (.com) are taken.

I don't want to babble a lot as I'm not that experienced when it comes to earning with Adsense but I wouldn't mind extra income. I've read eBooks from time to time but nothing really seemed to work.
