How much do you make with autoblogs?

Is it worth to make about 100 good autoblogs with caffetein content, translated feeds or whatever, and just leave them?

What is your success rate of earning blogs from 100 made autoblogs?

Or do you always also interlink your autoblogs for better success and put up some backlinks?

I'm going to start with something new in January 2009 and I'm not sure, if autoblogs are the right thing for my expectations.
