Google Experimental Lets You Make It The Default

Google Experimental, the Labs site where you can test Google search user interface prototypes, became a lot more useful when Google added the ability to “Join the experiment”. By clicking that button, the particular experiment will become part of your Google search experience whenever you search on the regular Google.com. Since the experiments conflict with each other, you can only join one at a time, but if there’s one that you really like, here’s how to make it a part of every day.
