Hello fellow passionate IMers, A bit of dilemma in web 2.0 backlinking. I'm getting an impression of creating a fresh tumblr blogs, livejournal blogs, blogspot and other popular web 2.0 is not as effective then registering an expired tumblr, blogspot which have a bit of page authority. People also complain of creating fresh web 2.0 take a very long time to rank and sometimes don't. Is this true? What I felt was having diversity is the key which means having own set of expired web 2.0 domain to registers didn't have much of an effect. Backlink diversity meaning creating links on document sharing sites, forums etc.
