Hi Guy,
I am strongly agreed with WoProt and i am disagreed with Growrich on seeting once you will start banking huge check from adsense and affiliate programe, this all B***S and hype. To be success in any of the online business, you have to work hard and learn everyday. There is no overnite millionaire thingy.
As for the content, rss feed is a way but not for long because your subcribers will get tired after a while, the best way is writing your contents. The search engines love unique contents. There is no automatic blog....
Hope that's help.
cheers
