Here are some great monetization related posts that have bubbled up in my feedreader lately:

Vizu just launched a new service where they pay you to post polls on your site. You provide some basic demographic information for your site, and they will pay on a CPM basis for placing the poll on your site. This could be a great strategy for some of the quiz sites or even my friends who run a popular teen site, Kiwibox.com.

One of the blogs that I found off of the wickedfire forum has a good post about calculating confidence intervals for your PPC campaign performance. This is the best way to statistically prove if your initial campaign results are statistically meaningful, or if you need to continue testing your campaign. When I get around to building out the MonetizeTraffic tools section, I am thinking about a quick and easy interface to calculate confidence intervals. If you want to geek out on stats, you wikipedia has some good info.
I really liked this post on Earnersblog about combining blogger accounts with social bookmarking promotion to drive easy affiliate sales. The posts mentions using Bookmarking Demon to automate the bookmarking. The software looks very cool, but it is $97. To do it on the cheap, you might want to check out Delicioso which has less features but is free.
