So, after reading this discussion I headed over to the
Rss scraping and Autoblogging thread. I've dicked around with affiliate marketing for about a month, and never really had any money making experience before that.
Decided to run a few tests with wp-autoblog and adsense, I've made $3 from in two weeks with one autoblog. Crappy amounts (although it's enough to pay for my hosting), but I'm only running one, and plan to run more. At the moment am focusing on tracking and analytics for that, so I can get it right for the other 1000 I'll probably end up making. Definitely need wordpress MU though.
Anyway, thanks for the thread.
