The most commonly used phrase after ‘first!” on discussion boards or article comments especially is ‘+1′, a quick and short way for a user to agree or ‘like’ the above article or comment. Inspired from this manual concept of ‘liking’ something on the Internet without having an actual ‘like’ button, Google has rolled out a similar feature for its search engine. Yup, soon you will be able to +1 your search results. And it is actually called +1, by the way.
So here’s how it works: Once you have a public Google profile up and running (which you probably already have), you can +1 a search result which will be then shared with your Google friends. So, for example, if Jane has +1′ed a search result for a recipe, Sarah, who is a friend of Jane, will be able to see which link she liked and be able to find that particular link faster.
Currently, the feature is restricted to Google search results but the company is promising to embed the feature on other Internet objects soon.
