Interesting Google Feature

As you might have noticed that I use Google Adsense on my blog. I don't earn much money, but I like to use it to see what kind of ads are presented on each topic. The most impressive part of Google Adsense has always been about the way it automatically detects what ads to show. Context senstive ads helps publishers in having relevant ads on their sites helping them make money. Of course, it can go horribly wrong sometimes, but generally its okay.

So, today I was very surprised to see this on my blog.

It seems Google has introduced a new feature where you can simply request an ad for a particular topic instead of the Google guys doing it for you. Or does it mean they got no clue on what to show and therefore decide to ask readers of my blog? The last post was about acting. So when I typed acting in the box, it took me to this page.
I can't understand why the same ads could not have showed up in the previous page? Interesting days these are.....
