Had an interesting conversation with another SEO today and wanted some other opinions. I recently did a very successful viral widget campaign that was heavily adopted on livejournal and blogspot blogs. I've heard conflicting information on how muc links count from blogs hosted on the same domain. xxx.blogspot.com or xxx.livejournal.com etc. I've heard that only a couple of these blog backlinks will count. I'm confused as to how this could be true, because if it were, that would make almost all blog links out there nearly worthless, and nearly impossible to rank. I'd love to hear other opinions. Thanks
