This will not give PR 6 LoL. I have thousands of quality pages in my site and getting 2000 uniques per day still PR 4. So, we cannot count by numbers.
IMHO, PR doesn't really matter. Now, I am no Guru, I personally, own, a couple of sites that are on page 1 of google for specific keywords. those sites are PR0 and PR1. Granted the keywords are relatively low volume,a few thousand searches a month. I would just focus on building quality links and the traffic will come. Brian
