It’s becoming clear that social interactions is what’s been missing in current search engines. However, with Google +1 it seems like the gap is about to be filled.

Why search engines go social?
There is many reasons for search engines to become more social. You know why?

• The major reasons is to be able to show users what they like and want to see. If users tell search engines manually what they like, it’s possible for Google to be more accurate with what they show.
• People like to interact with content. They already do it with Facebook likes, so why not with Google +1?

What do you think about Google’s latest move to go social? Should they continue to become more open and let people click what they like, or should search results be algorithmically driven?
