Part of the AIM network, it's another online application to create and share timelines. As I've said before, timelines are very intuitive in displaying both data and information, so it's not surprising that these applications are springing up. The circaVie user interface feels a bit easier than xtimeline, and I like circaVie's style and design a lot more too. In particular I like the timeline scrolling; it feels a lot like the iPhone interface. Try it out for yourself using your AIM screenname.
