Thank for outlining the above points.
I also think E-learning as an effective tool, as you can learn, when and where ever you want.
One major component I'm a bit annoyed of is the missing personal contact with others. Sure, you can have skype meetings and so on, but I think the personal component is also crucial for a learning success.
I think the issue with information overload also concerns the "offline" learners, as people tend to start too late and therefore exaggerate a bit due to time constrains
