Asynchronous communication
Asynchronous communication is an important element in my discussion board for online students. Being able to enter into a discussion posting area at any time of day or night is a fantastic benefit of this form of communication. Educational technology for the support of asynchronous communication is necessary (Han, Nelson, & Wetter, 2014).

Thank you for your great comment.

Heidi,
I agree with you. Asynchronous interaction is the benefit many students are looking for regarding online learning. It doesn't mean you have to give up interaction and communication.
