http://www.lithman.net I'm selling 4-6 125x125 ad spots on my werbmaster blog. They will be in the sidebar where the current 125x125 ads are (such as the hostgator and godaddy blocks). This is a popular blog among webmasters. Gets anywhere from 60-100 uniques/day and has 100+ RSS subscribers. It is currently a very strong PR4. I'm even on www.johnchow.com's friend list! I'm also selling a 728x90 ad in the header. All prices are $15/mo.
