I think that is a big problem for many of us. We tend to thank that because we work online we don't have to deal with people.
In reality, I think we can compare it with having a brick-and-mortar business. If you were to be shop a shop owner and potential customers come walking in, yet you just sit there and make no attempt to communicate or assist them, people will just turn around and walk out.
Even though we do not meet people face-to-face and people can leave comments/messages 24/7, we still have to communicate and build those relationships.
