Yes, indeed, the rumors are true: I resigned from Oracle a week ago (April 2nd). I apologize to everyone in St Petersburg who came to TechDays on Thursday expecting to hear from me. I really hated not being there. As to why I left, it’s difficult to answer: just about anything I could say that would be accurate and honest would do more harm than good. The hardest part is no longer being with all the great people I’ve had the privilege to work with over the years. I don’t know what I’m going to do next, other than take some time off before I start job hunting.

Google’s terms and conditions are extremely strict such that lots of web publishers cannot use adsense adverts on their sites. They are either denied from joining the Google AdSense program, or in a condition that is becoming more and more ordinary do not wish to do dealing with Google. A number of publishers are also finding their Adsense accounts are being disabled for reasons that are totally beyond their control. The quandary is that most of the alternatives to Google’s Adsense are pretty inadequate. Most of the good ones (such as doubleclick) are only involved in very large volume customers and so are not attracted in the little guy with his blog who needs to earn a little revenue on the side. For this cause I have compiled my Top 10 alternatives to Google’s Adsense that are perfect for the small time publisher.
