+1 is making its way into Google search results. This means that soon you will be able to “rate” links or ads you find useful and this will be used to tell your friends about the value of that site. Recommendations are filtered to make them as relevant as possible, while people within your social sphere (Gmail etc) get a higher priority.
This will no doubt help Google to improve their social network side and maybe stick it to Facebook just a little bit. The +1 button will start with English Google search and ads soon. Me? I give it a -1. Are we replacing relevancy with popularity? Probably not since Google wouldn’t want to kill it’s moneymaker, but still, this seems like a road better not taken. Popularity does not equal relevancy. I guess we will all see how this goes.
