Open DNS is a free service with a number of cool features for making your web surfing easier and/or safer. The options can be turned on individually. Some of these are especially useful for people who want to protect their children from stumbling onto bad stuff.
The only downside I've run into is that sometimes using Open DNS breaks the ability of Content Delivery Networks to determine your location, and therefore can cause issues with downloads from iTunes or streaming from Netflix.
