Check out the invisible “Like” button that Google has created.
I guess Google released the “Like” button and we didn’t know it. Kind of sneaky. 
Check out this article.
Another day and I read another post on how Facebook’s Like button is slowly obliterating Google’s Link as the next currency of the web. The pondered question in this case is what is going to be Google’s counter-offensive against the Like.
The assumption is that Google as a search engine has worked on the principle of ranking web pages according to the number of other pages linking to it. Well, here’s the deal: when a person likes something on the web, in most cases, a link is created. Google can see this Link, and hence can understand and incorporate the Like, in its scheme of things.
This mechanism has already been publicized by Google, but I’m surprised how many folks still keep discovering it as if it were something new. For example, see this from yesterday.
