when Tornado was first released, there was a lot of discussion online on various forums and comment threads about why it wasn't built on top of Twisted, or why it was a complete separate project. I tend to agree with Brett Taylor in that Twisted was too large a project to suit the goals of Tornado, and that its own divisions within twisted.web were difficult to navigate through the event handling part of Tornado is less than 100 lines of code and is a lot easier to implement and understand than Twisted, although Twisted also serves a purpose. I like and prefer that Tornado is self-contained and focuses on a single use case (returning JSON in long-polls) and does it well
