Hi! Im about to start a new project and new case study with keyword with 2m global and 1m local searches and med/hard competition (quite easy as for as many searches). Im planning to make 20x web 2.0 as first tier,xx/xxx private blog posts as second tier and dripable as third tier. So now im asking : what's best private blog network? I need at least 100 posts and i need to get the links cause i want to set dripable. thanks!
