What you propose I guess could work. It seems like it might be a bit of work setting it up and maintaining it.
Personally, what I think that I would do if I have a $500 a month content budget is pay for some better quality articles and put it on my main site. Then make sure that content is linked effectively to the money making pages on my site.
But that would work better for me because my site is an ecommerce site and I sell stuff. I am sure it wouldn't be as effective for sites that generate revenue primarily through adsense or affiliates.
The problem with 10 blogs on 10 sites is that there is no link synergy working together. Site A gets a few inbound links, and Site B gets a few inbound links, and Site C gets a few inbound links, etc...
But getting a "few" inbound links each probably won't move ANY of them high enough up the SERPs to start getting natural links.
On the other hand, if you concentrate on one site, with all your link building going to that site, then it will have a chance to rank higher based on inbound links, and will thus be more likely to attract natural links.
Also, google tends to like sites with LOTS of related content on them. And it likes to see SMART interlinking between the pages on them. and your visitors would like the, too.
Specifically, a site might rank well for a long-tail keyword, but I don't know how many people will click on the adsense ads if the site doesn't look top notch.
don't get me wrong; there are plenty of people out there that do what you suggest. But most of the people who do it that way SEEM to use automation to scrape articles, spin them, and re-post them as their own.
They also tend to host them on blogger or wordpress so there are no hosting fees, domain name fees, and they don't have to spend man hours updating their software each time wordpress releases an update.
So if you are going to go the "legit" route, I would personally focus on one niche blog (I would put it on my own site), and put the best content and get the best links that I can to that site.
If it is successful, maybe branch out from there.
Hope this helps. But get other opinions first before making any decisions.
