Hello.

I've always been a fan of Yahoo's developer APIs due to their generous usage limits and flexible terms. However, recent changes to their T&Cs are concerning. They now prohibit displaying ads alongside Yahoo API results unless they're Yahoo Ads, and they forbid showing Yahoo search results next to other search engines' results. This impacts sites like Topicala.com and gada.be, as well as many example applications using Google AdSense. While their RSS feed search terms seem more lenient, allowing aggregation with other results and ads, the overall tightening of restrictions stifles innovation. I've updated Topicala.com to use the RSS feed as a workaround. I'm disappointed with Yahoo's approach, as proper attribution should be sufficient, especially when sites like mine prioritize Yahoo results. Until the licensing becomes more flexible, I can't recommend Yahoo's APIs.

I've just added a Google AdSense referral link to my blog! Google recently updated AdSense, including their terms and conditions. While I spotted mentions of "Feeds" and "Referrals" in the new terms, I haven't yet seen Feed Advertising in action. If you're interested in monetizing your blog, give AdSense a try!
