This is a lightweight library (less than 3kb) and dependency-free, it means you can implement in any webpage, it doesn't matter whether you use jQuery or not. I feel that there are no reasons for such a simple library to be jQuery dependent.
TitleNotifier.js has a very simple and intuitive API, it has only 4 methods. So it couldn't be easier to get started. In the github page you can find the Getting Started guide and in the project page you can see the live demo.
If you have any suggestions for improving TitleNotifier, please feel free to fork it and make a pull request with your changes.
