Is it possible to help the main site rank higher if you link from several blogs within the niche? Wouldn`t that gimme lotsa niche links? Yes, I know of differnet IPs, c-class and all that crap. But if I visit a friend and set up a Blogger site, then I go home and set up a Wordpress blog, and then I visit another friend and set up a Blog.com site. Possible? Am I missing something? I can still do postings on all of them from the same IP, right?
