Wow, how do you maintain so many sites Nintendo? Lots of them sound as if they're self-maintaining, but do you need to do regular maintenance on your public domain and message board site(s)? In terms of my personal performance, I averaged over $11 a day last month.
Video game sites: I stoped updating them about six months ago. AWS/affiliate sites: Make them and hardly ever touch them again. Message boards: Don't need very much work. One back-up a week. The Public Domain one probably requires the most work. In the last three hours alone I've downloaded 734 megs of Earthquake/Mount St. Helens government images and see gigs more on the way!! (Having DSL and your own web crawler, aka WackoBot, helps BIG time.) Doing this full time also helps big time!
I average less than a dollar each day One of my sites gets 100-200 unique visitors per day, though...
