A couple of weeks ago, we made the search box on the Google homepage bigger. Most people who bothered to comment on it seemed to be grumpy. This is understandable – users tend to prefer familiarity, particularly when the interface is something they use every day to accomplish a task. But people are also more likely to speak up when they have a complaint. Overall, people actually like the bigger search box.
Although this is a very simple idea and an even simpler change, we're excited about it — because it symbolizes our focus on search and because it makes our clean, minimalist homepage even easier and more fun to use.
