Google PageRank upgrade

Imagine my surprise a few minutes ago when I made a visit to this site and noticed my Google PageRank had increased to a 1! I really hadn't expected this site to ever improve in terms of PR as this site has migrated to a payperpost, blogitive, and miscellaneous topic site. I've been throwing in some filler between payperpost posts in order to fulfill their requirement of not having 2 payperpost posts back to back. This improved ranking will help with my opportunities in payperpost as I will now qualify for more. The past few weeks have been tough catching opportunities that I qualify for before other bloggers claim them as the opportunities for pages with a PR of 0 are very limited. Another benefit is that the opportunities that require a PR of at least 1 also come with a slightly larger payout. Now I need to improve my ranking on my other sites so I can attempt to monetize them.
