Besides being able to keep people busy by constantly checking out on your latest status, I have long ago thought about the possibility of using Twitter or micro-blogging services to help with managing some software development collaboration challenges such as issues management, new feature requests and etc. It is possible.

It also offers APIs for integration with other software as well as specialized hardware. It is created for corporate.
