I'm thinking about offering up those types of lists respectively for sale, and I'm not sure what they would be worth for potential buyers. Now, nobody say "they are worth what people pay for them" as that is obviously true...I'm looking for a general ballpark figure as to what most would find an acceptable amount to pay for lists of that size. Here are the specifics: I've got a list of just about 3k auto-approve blogs. The root domain of every single one has at least a Page*Rank of 1 or higher. I then went ahead and scraped every single blog post from every single domain. That has left me with well 2,000,000 UNIQUE blog posts (and counting, as I'm still scraping...I still have over 1,000 blogs left to scrape every blog post from...you do the math.) I plan on (when I'm finally finished scraping all the blogs posts) also checking the Page*Rank of each and every URL. What would lists of auto-approve blogs of that size be worth paying (with and without Page*Rank of individual posts)?
