I find what an online classroom can provide is a refreshing lack of 'he said/she said.' Students are not distracted by what their classmates are wearing, their skin tone, or in-class relationships. This change can allow the student to concentrate more on the assignment and learning.
However, since humans are social creatures, it is still important to develop some sort of online culture to provide encouragement and stress relief to the classrooms. Without physical measures to judge by, these communities are more 'pure' with their interaction than what a physical based classroom can provide.
