I think it has more to do with an engaged instructor as well. I've had one class where the instructor was engaged with the students, asking questions and making us do research outside the requirements, I really enjoyed that class. I've also had a class where the instructor changed the name in the reply, and it was the same reply to a bunch of students, with the same follow up question. That class was something I did not enjoy, even though the topic of the class was interesting. I've also found that almost half of the students in my classes shouldn't be in college, or they simply don't follow instructions well. Maybe it has something to do with my military background, but most of my posts take a while for me to post, simply because I take the instructions and try to match them up with my post. The hardest part is trying to keep them under a word limit, because as you can see with this wall of text, I like to type a lot.
