This is a new webapp I've built to handle a specific question in usability testing: how long does it take the average user to find a particular bit of information (like a phone number or an address) on your website? I built it after seeing too many small business website that had important information hidden away at the bottom of a web page. Questions/comments/suggestions/typos appreciated!
Graph Your Inbox is a Google Chrome extension that allows you to graph Gmail activity over time. You can use it to visualize your communication with friends, your Facebook activity, when you purchased items on Amazon or how often you use certain words or phrases. We provide the same search functionality used by Gmail, but instead of a list of messages we show you graphs of email trends over time. [more inside]
