Would you mind sharing your stumbleupon user name with me? I would love to follow you and your shares! :) I am beginning to get more active on SU and it is definitely paying off. I have had a few posts in the last several weeks that have brought in 600-700 visits each. :) In regards to your "challenge" I am going to try out paper.li I will let you know how it goes.
This is the number of views that you can test each month on your website.It's up to you how you choose to use them, either by allocating all the views to one test or to multiple test, either on one page or on multiple pages. If you have selected the 10.000 tested views plan and you run an experiment on your category page which is viewed 7000 times per month, then at the end of the month 7000 is what you'll be counted as tested views quota.
