Chrome: Ever wonder exactly how often you visit your favourite sites in a week? Back Again? is a simple Chrome extension that tracks that data and shows you a small counter.
Back Again? is super simple, but it has a weird effect on your browsing in general. When you see the actual statistics on the sites you regularly visit, it makes you think about what you're doing there so often. Whether that actually changes your habits is up to you, but it's interesting nonetheless.
