I'm just a stupid newb, but wouldn't it be easier to set this up on one or two, or even 50 domains. Like an about.com setup? Just have adsense and affiliate link riddled pages about everything, all interlinked and get directory links to each individual article page?
Wouldn't the Google bot like that better than all these one page, two paragraph auto-generated sites?
I'm probably stupid for even asking this, but I just don't have the money to spend on 2,000 domain names. Even if they are 99 cent .info names. I guess I could do like 200 a month, but wouldn't it be easier to group them on one wordpress installation?
