Latest from Google. Custom search engine.

Yes, Google after the You Tube is once again in light. Once again their team is followin, what Sergey told them, 'Features not products'. And they are really concentrating on it. First it was reader( of which I am an addict) and now it is co-op. Though this Co-op is a kind of new product but it still take root from one very popular product of Google. Their search API. Yes now they have launched a search API which one can tweak to bring results from selected sites. Great...
Oh not that great because its already being done by other players like Yahoo. But still when Google is attachedto some product, then it also have some different halo. And let me tell you that Googlers knew it beforehand and they integrated it with another of their service of which google make its bread, yes guessed rightly; Ad-Sense. It would be an ad supported thus opening another stream of revenue for yoursite and blogs.

The baest part of it is the integration with Adsense.

I am waiting for google ad integration for videos, because now they have biggest library of user generated video in form of You Tube.
