The large variety of content given to study. I enjoy the various sources for the content and like the fact I can see other articles people I am connected with are reading. I have come across some interesting articles. I also like the that I can track a number of other learning sites that I use. It covers most but not all of the on-line learning portals. The ability to customize your own learning plan is also a nice feature that I am still developing - this really forces you to think about what your goal is and how to reach it. Tracking your progress is nice and does help you see if you are getting to the place you want to be.
