I was a "self-directed" learner.  This to me, meant that I was comfortable and confident in managing my time and committment to the course, but that I also liked the availability and feedback of my instructor and peers.  I enjoy face to face time, to help clarify any misunderstandings, but with a busy schedule, know that I can obtain those clarifications through the use of email or discussion forums.  I think that's what makes online learning so successful, the ability to communicate when needed.
