By now you’ve heard about Google’s new social search feature called +1.The idea is that you’ll end up getting better results when your friends share good results with you. So, by clicking a +1 next to a Google result, you’ll be sharing your preferences as well.

Thanks to Google’s notoriously slow rollout of new features, there’s really no telling as to when you’ll get the +1 feature for yourself. Fortunately, Google is providing an opt-in to at least speed up the process somewhat, via its Google Experiments page.

All you have to do is head to that page, then select the +1 button “Join This Experiment” option. Once you do, you’re presumably added to the list of people who want to take part in the feature, and it should speed up the process for you.

Please note, it may take a while before you see the button in search results, and it may occasionally disappear as we make improvements.

Once you do have it, this is what you’ll see:
