Here is the thing. The root domain is www-xxx-edu which has pagerank 7. And they have WordPress-mu hosted at their blog.xxx.edu which has pagerank of 4. The individual wordpress blog (home page) is at blog.xxx.edu/~username/ I happen to be able to create unlimited users (wordpress blogs) on this blog.xxx.edu domain. Do you guys think there is some value in this? BTW, I wouldn't do anything blackhat or illegal (including adult stuff) on these blogs as that would jeopardize my career.
