Google +1 button

When searching on Google, I just found out that they now have ? +1 button right at every result... I don't know how long had the button been alive but anyways what do you think of the Google +1 button?

I haven't encountered this Google +1. Do you know something about it?

i think that this button is show web page ranking

I have read this critic about this +1 button. It says there that +1 button is like a button you push for but you're not really getting that treat. One major factor of this code is it allows your page to get a higher ranking but the turn out is opposite. I actually don't know +1 button because I'm not getting in use of it. So, this critic may have in fact a basis.

Google +1 button is new feature introduced by Google to enhance the personalized search experience.
If user +1 your webpages, this means he is considering your page worth sharing in his network.
+1 button can act strong weapon for your website.
Moreover this button helps in increasing your search result rankings.

I like the Google + button. It doesn't really add to your ranking, it's more of a recommendation from other people. If they find out a site is good, then they're recommend it if they found it interesting wouldn't they?

Google, on the rare occasion, may up your rank if your site gets like..1/5th most searched site in the world or so. People confuse it for upping your rank in Search Engines, it doesn't, it just gives you the benefits of promotion though.
