Starting today, we're going to be experimenting with adding some ads to certain pages in Cookbooker to help pay for the hosting of the site. The Challenge page, cookbook pages and some other places will see Google Adsense ads. I hate websites which are cluttered with ads, so they're going to be modest in number and placement, and I've opted out of all the objectionable categories you can opt out of (get-rich quick, adult services, politics, weight-loss etc).
I can see offering an ad-free membership for a modest annual fee as an option. Let me know if that's something people might be interested in. I'm also open to other options to bring more value to the site, things which might be worth paying a subscription for.
