Google's +1 Button Adds A Social Element to Search

As if you needed another, here’s one more reason influencers are so important.

Google has introduced the +1 button, which will be rolling out broadly over the coming months. Clicking on the button allows your friends and contacts, pulled from other Google properties like Gmail, to see your searches. Eventually, you’ll be able to plus one pages, basically making all sorts of recommendatins to your contacts. Mashable asks a marketing-related question specifically:

Can marketers game the system by running “check +1 to enter” promotions?
It seems that Google frowns on this sort of thing, but it’s unclear whether the company expressly forbids it.
