Hi, So I have a question. I've spent a bunch of time getting cozy with Scrapebox, in order to target the Tumblr platform. I ended up scraping a whole bunch of Tumblrs, some from BHW here, and a hundred thousand or so from the SE's. Using the usual suspects I checked them all for availability, PR, SEOMoz metrics etc. So here's what I've got a list of now. 400+ Available to register Tumblrs PR 1-3 PA 25+ My question is, what is the best use of these? I was *thinking* of using them as Tier 2, for my Web 2.0 network. Hoping that the PR will flow to my Web 2.0's and give them a significant boost.Does this sound like a decent use for these Tumblr's or am I wasting them? What would you suggest? Looking forward to hearing your experience.
