I am selling 150x150 ads in the sidebar of the popular blog: openaccessblog . com. The blog has received 6,702 visits over the past 4 days, and was averaging about 30 visits a day before then. Over the past 4 days, the direction of the blog has changed, and thus more visits are coming in. If requested, I will PM traffic stats. Most traffic is referred, and are interested in science/politics. The blog is a PR4 as well. Price for a 150x150 banner per month: $20. PM me with your site title, image, and link, or post it here.
