Hi there! I want to build a few dozen blogs to PR4 and use that as link bait for linking to main site. Is is ok to put all those blogs onto wordpress.com or should i spend extra money and effort to host on various other free blog hosts like blogger.com... if someone gets a link from abc.wordpress.com and another link from xyz.wordpress.com does that count as 2 valid links or because they share the same domain it's discounted? maybe if i offer websites a link from abc.wordpress.com and other from abc.blogger.com that's better for him so therefore he'll take my linkbait more seriously i need good advice here, please help, thanks
