On-line Learning

I think divide in the digital world also has to do with being in a comfort zone. I look at all the on-line classes that are now available and some people choose to take them but not me. I like the instructor at a personal level approach. Why -- maybe it is because that is what I am use to. Or could it be I feel the on-line approach as being to cold and impersonal? I have yet to take an on-line class and maybe I just need to try one!!!! Any thoughts?????
