I'm currently testing it. Far better payouts than YPN, less than adsense (rough estimate, 2/3). Excellent ad layout program and competitive ad per-site filter(s) - you can customize ads, including all display fonts sizes, bold, italic, etc., and even custom gradient backgrounds. The admin features are far superior to what adsense has. MSN must also approve every site before ads run on them, so if done right, they will maintain a higher quality of sites running ads, which should attract more advertisers. The real problem is that they don't have near the ad inventory of adsense, so CTR is about half compared to adsense. The admin was real buggy at first, but seems to have improved in the last few days. Could give adsense a run for their money if they get the advertisers - which would improve payouts and CTR. A much better effort than YPN - which is now a complete joke imo.
