Welcome to the Q&A Forum

why would you have so many blogs?  it's creating a false link network.  None of the ranking that any one of them could possibly get would even come close to the ranking strength the main site would get if you keep it all self contained.  Then there's the problem with partial duplicate content conflicts, the need to maintain them all, and the potential complete failure down the road if you ever need to change domain names or technology platform on any of them. It's about the least effective solution I've seen (and I do see a lot of people do it) done by people who think they know SEO yet where I consistently run circles around them by using a much cleaner self-contained approach. Now if you wanted to have separate subdomains or entirely separate root domains for each of several topics, where each one has completely unique content dedicated to the topical focus of that subdomain or root domain, you MIGHT get some benefit out of that, but in reality, that path is for very rare and extremely complex needs only and not to be attempted if you don't know your stuff at the highest levels... Better to keep it all self contained - every inbound link to any page, article or section not only benefits that page/article/section, but the entire site gets a boost.  And users don't become confused.

Wordpress isn't very secure - even with the security plugins and such you can  leverage. SEOMoz has some great content on the subject of subdomains vs sudfolders...what can impact being able to use that is if the blog is hosted on a different server than the TLD and if so, if the domain mapping can work to point the blog to the subfolder/subdomain is Google sees it as being associated. This is a challenge for some systems (including mine, even though in theory it should work). Sudfolders are the preference. http://www.seomoz.org/learn-seo/domain

Cyrus, that is exactly what I was saying. Thanks so much for the help you really did save me the trouble of trail and error on this one. I also appreciate the help from altecdesign and dogmatic69.
